Reason (R): The scattering of red is least

Select the right answer with the help of code given below.
Code:

  1. Both A and R are true and R is the correct explanation of A
  2. Both A and R are true but R is not the correct explanation of A
  3. A is true but R is false
  4. A is false but R is true

Answer:

Option A: Both A and R are true and R is the correct explanation of A

Detailed Solution:

The correct answer is “Both A and R are true and R is the correct explanation of A”.

Red is used for danger signals because it has the longest wavelength of visible light and scatters the least in the atmosphere. This allows red light to travel long distances without getting scattered, making it easier to spot and avoid danger.
