PHYSICS [2 Mark Question Answer]

Its a “Diverging-beam”, meaning, the rays originated from a point and spreads in all directions. Divergent beam is produced by a torch. Divergent beam of light.It is because of diffraction of light. A torch produces divergent beams of light which enters into the shaded portion.

Searchlight = extremely bright spot, illuminates even further away, and probably, due to the power, gives some wide area coverage too.
Spot light = narrow beam, gives a longer throw, illuminates objects further away.

Those bodies which do not allow the light energy to pass through them, are called opaque bodies. Opaque bodies are not called an opaque medium because they do not allow light energy to pass through. Four examples of opaque bodies are bricks, stones, wood and metals.

Non Luminous Bodies do not emit light energy of their own but reflect the light energy falling on them. For example, metals, stones, trees, bushes, furniture, houses etc. Moon and planets do not produce light of their own, they just reflect the light of sun. So they are called non-luminous bodies.
