Answer the Following Questions.

Question 1.
Classify the following objects into transparent, translucent, and opaque:
Cardboard, duster, polythene cover, oily paper, glass, spectacle lens, piece of chalk, ball, table, book, window glass, palm, school bag, mirror, air, water.
Which type of materials do you find more in your surroundings?
Answer:
A. Transperent Objects: glass, spectacle lens
B. Translucent Objects: polythene cover, oil paper
C. Opaque Objects: cardboard, duster, piece of chalk
I find opaque materials are more in our surroundings.

Question 2.
We can’t identify the type presence of completely transparent objects even in light. Is it correct or not? Support your answer.
Answer:
Yes, we can’t identify the presence of completely transparent objects even in Light. Because it allows light to pass through it. So we can’t find it.

Question 3.
Why can’t we see objects which are behind us?
Answer:
The reflected light behind objects of us can’t reach our eyes. So we can’t see objects which are behind us.

Question 4.
What is required to get a shadow of an opaque body?
Answer:
To get a shadow we need

1. light source
2. opaque body
3. screen.

Question 5.
Can we use a plain mirror as a rearview mirror? If not why not?
Answer:
No, we can’t use the plain mirror as a rearview mirror. Because the plain mirror can’t cover all objects behind the vehicle. So we use the concave mirror as a rearview mirror.

Question 6.
Why do we get shadows of different shapes of the same object?
Answer:

1. We get different shadows for the same object.
2. because shadow shape is changed depending upon the position of the light source
3. and angle position of the object.
4. So we may get different shadows shapes from a same object and same shadows from different objects.

Question 7.
What are the differences between a shadow and an image?
Answer:

IMAGE	SHADOW
1. Images are colour full.	1. Shadows does not have colour.
2. Image is formed due to the reflection or refraction of light.	2. Shadows are formed when opaque objects obstruct the path of light.
3. Image gives more information such as colour, structure, etc. about the object.	3. Shadow does not provide any details about the object but it gives an idea about the shape of the object.
4. An image in a plane mirror doesn’t change in size at all; it is always of the same size as that of the object.	4. Shadow size may be changed depend on light sources position.
5. An image in a mirror can be seen without a screen, whereas it is mandatory to have a screen to form a shadow.	5. A dark patch formed on a surface behind an opaque object placed in the path of light is called a shadow.

Question 8.
Malati noticed changes in the lengths of her shadows during the daytime. She had some doubts about this. What could be those doubts?
Answer:

1. Why shadows are always black?
2. Why sometimes shadows are small and large?
3. Why our shadows always follows us?
4. Can we guess the time when see the shadow?

Question 9.
How can you explain the straight-line motion of light?
Answer:

1. Observe the objects, the formation of shadows and the path of light as shown, in the figure.
2. Similarly draw the shadows for the objects given in the fig. Extend the path of light and draw a shadow on the given screen.
   
3. We have drawn arrows in the above figures assuming that light travels like rays that are straight.
4. We can predict the shapes of the shadows only when we consider that light travel as rays along a straight path.
5. In ancient days, by observing the shapes of shadows people came to an understanding that light travels in a straight line.

Question 10.
We would not be able to see any object around us if light does not get reflected. How do you appreciate this property of objects?
Answer:

1. Vision is the vital sense to organisms.
2. Its possible by light reflection.
3. I feel wonder by this phenomena that provide the vision.
4. I also feel happy by seeing beauty nature by light.

Question 11.
Where do you find reflection of light in your daily life?
Answer:

• Due to the regular reflection of light, we look at our image in the plane mirror.
• We can turn the sunlight towards dark places by the regular reflection of light with the help of a shiny surface.
• The wing and rear-view mirrors of a car are made of a convex and a plane mirror
  respectively.
• A microscope uses a mirror to reflect light to the specimen under the microscope.

Answer:

1. I find that glass slab does not form a shadow.
2. I observed the shadow of my hand.
3. It means glass slab is a transparent object and hand is opaque object.
4. My conclusion is that only opaque objects form clear shadow.
5. And transparent objects does not form shadows.

Question 2.
If we focus a coloured light on an opaque object, does the shadow of the object possess colour or not? Predict and do the experiment to verify your predictions. (Coloured light can be obtained by covering torch glass with a transparent coloured paper).
Answer:

Between an electric bulb and a tube light, which forms sharp shadows of objects? Do an experiment to find out and give the reasons.
Answer:

1. Between electric bulb and tube light electric bulb forms clear and sharp image.
2. Electric bulb is round in shape.
3. It takes more voltage and forms intensity light
4. That’s why electric bulb forms sharp and clear shadows.
5. But at the tube light shadow it is not sharp.
6. Here light source is lengthy.
7. And light fell on objects from different side.
8. So the shadow does not sharp.

Question 4.
A mirror is kept on the wall of your room. Your friend is sitting on a chair in that room. You are not visible to him in the mirror. How do you adjust your place so that you are visible to your friend in the mirror? Explain.

Activity – 6

FUN WITH A MAGNIFYING LENS        (Page No. 123)

6. Take a magnifying lens and try to form an image of a tree on a white drawing sheet.

Answer:
I notice that the image formed through the magnifying lens is clearer than that formed with a pinhole camera.

iii) Can you find any other differences or similarities between shadows arid images? Write in your note book.
Answer:
Similarity:
Shadow and image are related to light.
Without light both are not visible.

Difference:
The key difference between image and shadow is that the image is the reflection of the light rays by an object, whereas the shadow is a dark shape projected onto a surface when an opaque object obstruct the light rays.
The term image generally refers to an optical representation of a real object. A shadow is black in color while an image is colorful, and represents the real colors of the object it represents.

Activity – 7

OBSERVE THE REFLECTION  (Page No. 124)

7. Make your classroom dark by closing the doors and windows. Ask one of your friends to hold a mirror in his hand. Take a torch and cover its glass with a black paper leaving only slit in the middle. Now switch on the torch and adjust it so that light falls on the mirror in your friend’s hand. Ask your friend to adjust the mirror so that the patch of light falls on another friend standing in front of him at some distance.

i) What do you observe from the above activity?
Answer:
When light falls on any object, it rebounds back. This is called reflection.

ii) Ask your friend A to cover the mirror with a book. Now switch on the torch and focus it on the book, Can you see the patch of light on your friend? Why?
Answer:
When mirror is covered with book I can’t found patch of light on my friend. Because the surface of book is not smooth as mirror. On smooth surfaces reflection is effective.

iii) Did the light that fell on the book not get reflected?
Answer:
The light fell on the book is reflected. But its irregular reflection. Because the book surface is not smooth as mirror.
