(b) afternoon ?
Give the principle,construction and working of a pinhole camera.
give 4-5 examples of transparent, translucent and opaque
How To Make A Pin Hole Camera?
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
What is irregular reflection?
Moon appears bright at night. Is it luminous or non- luminous body? Give reason.
how does light help us to see things ?
in a pinhole camera why is the image formed upside down

A. Glass B. Water
C. Hydrogen D. Vacuum
Does the flame of gas stove emit light? Explain.
why is a shadow formed when an opaque object is placed in the path of light?
how are mirrors made?
explain construction &working of a pinhole camera
The colour of the shadow depends on the colour of the object . Is it True or False
can you also explain the difference between convergent beam , divergent beam , parallel beam and a ray
Which type of object scale is? (opaque/ transparent/ translucent)
How does a pinhole camera works ?
These objects allow light to pass through them.
These objects allow light to pass through them partially.
These objects do not allow light to pass through them.
One can clearly see through transparent objects.
One can see through translucent objects but not very clearly.
One cannot see through opaque objects.
Transparent objects do not cast shadows because they do not block light.
Translucent objects cast faint shadows as they block light partially.
Opaque objects cast dark shadows as they block light completely.
skin is translucent transparent or opaque
and hand is translucent transparent or opaque

We see the sun rising 8 1/4 minutes after it has actually risen .Why ?
Let take an example of the object around which light could bend,like water flowing around the stone in its path. Would such thing form a shadow? Justify your statement. Why?
A solid, transparent sphere has a small, opaque dot at its centre. When observed from outside, the apparent position of the dot will be ?
Pls give ans with explanation
