Question

Sunlight passing through a small rectangular hole may be called as:

• A. convergent beam
• B. divergent beam
• C. parallel beam
• D. none of the above

Answer 1

The correct option is B

divergent beam

Explanation for correct option:

Option B: divergent beam

1. Light rays from a point source are moving in all directions with time.
2. Such a beam of light is called a divergent beam of light.
3. Sunlight passing through a small rectangular hole may be called a divergent beam because they are moving in all directions after passing through the small hole.
4. Examples of a divergent beam of light are light coming from candles and electric bulbs.

Explanation for incorrect options:

1. When light rays from different points constantly keep coming closer together and finally meet at a point then such beam is called a convergent beam.
2. When a large number of rays travel parallel to each other, then we call such a collection of rays as a parallel beam of light Rays.

Hence, correct answer is option B.
