Question

Which of the following is the beam of light coming from the Sun?

• A. Converged light beam
• B. Parallel light beam
• C. Diverged light beam
• D. All of these

Hint:

Parallel rays are assumed in ray optics for sunlight because the Sun is extremely far away.

Answer 1

The Correct Option is B

Step 1: Conceptual Background: 
Sunlight travels as rays of light through space. Because the Sun is very far from Earth (about 150 million km), the rays reaching Earth are nearly parallel to each other. 
Step 2: Analysis of Options: 
(A) Converged beam: Rays meeting at a single point — not correct for sunlight. 
(B) Parallel beam: Rays remain parallel — correct for sunlight. 
(C) Diverged beam: Rays spread outward — also not true for sunlight reaching Earth. 
Step 3: Example: 
This is why shadows of objects on Earth appear sharp and straight, as the incoming light is parallel. 
Step 4: Final Answer: 
The beam of light coming from the Sun is a Parallel light beam.
