Answer:
(1) _Light_ is an energy which gives us the sensation of vision.
(2) Ground glass is a _translucent_ medium.
(3) Shadow is the dark outline of an object formed due to the blocking of light by the object.
If the light will bend around the object like water around the stone, the back of the object will be illuminated and shadow will not be formed.
(4) Pinhole cameras rely on light traveling in straight lines a principle called _the rectilinear light_ theory.
That makes the camera's picture appear upside-down.
And from the description above we can infer that the pinhole camera works on the theory of rectilinear light propagation.
(5) _Regular reflection_ takes place from a smooth or a regular surface.
