Question

Assertion (A): Red light signals are used to stop the vehicles on the road.
Reason (R): Red coloured light is scattered the most so as to be visible from a large distance.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.

Answer 1

The Correct Option is C

Red light is used in traffic signals because it has the longest wavelength and is scattered the least in the atmosphere. This allows it to be visible over long distances, making it effective for stopping vehicles. The statement about scattering is incorrect.
