Does the flame of gas stove emit light? Explain.
explain construction &working of a pinhole camera
can you also explain the difference between convergent beam , divergent beam , parallel beam and a ray
How does a pinhole camera works ?
Transparent objects
Translucent objects
Opaque objects
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.
Under `what curcumstances, a red shadow can be formed?
how can we make a kaleidoscope ?
why is the shadow of an object formed opposite to the direction of light source
can an object form two or more shadows at the same time ? How ?
What are the type of image formed in Cinema screen?
is cellophane opaque or transperent or translucent
what is a periscope
what does virtual mean
