• DIFFERENTIATE BETWEEN LUMINOUS AND NON-LUMINOUS OBJECTS BY GIVING EXAMPLES

Write difference between Transparent , Translucent and Opaque objects?

What the conditions are requried for formation of the shadow

why is the shadow of an object formed opposite to the direction of light source

How to make pinhole camera?

write an activity to show light travels in straight line

What are opeque, translusent & transparent objects

What is the principle of a pinhole camera?

State three charateristics of the image formed in the pinhole camera .

Show a diagram.

Give the principle,construction and working of a pinhole camera.

give 4-5 examples of transparent, translucent and opaque

1. If we hold a transparent object in the Sun,can we see anything on the ground that gives us a hint that we are holding something in our hand?
2. Changing the colour of the opaque objects does not change the colour of their shadows. What happens if we place an opaque object in the coloured light?

^{How To Make A Pin Hole Camera?} 

Q. An object, very big compared to the source of light is placed next to it. the shadow which will form on the screen is likely to have one of the following characteristics.

a. the shadow will consist of umbra only

b. the shadow will consist of penumbra only

c. The shadow will consist of both umbra and penumbra, but umbra will be faint as compared to penumbra

d. no shadow will be formed

....................kindly explain...........

We can't see the shadow of a bird or an aeroplane flying high up in the air, because:

a. the umbra doesn't fall on the ground

b. the penumbra doesn't fall on the ground

c. the umbra is very faint

d. no shadows are formed for flying objects

kindly explain.........

 What is irregular reflection?

State 3 condition necessary for the formation of image

which object reflection gives us clear images

how does light help us to see things ?

skin is translucent transparent or opaque

and hand is translucent transparent or opaque

in a pinhole camera why is the image formed upside down
