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
