Question

Assertion (A): The sky appears dark instead of blue to an astronaut.
Reason (R): Scattering of sunlight cannot happen due to the absence of atmosphere in outer space.
Choose the correct option.

• 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 A Both A and R are true and R is the correct explanation of A


The sky appears blue on Earth because the atmosphere of Earth scatters the most of the blue light from the white sunlight. However, there is no atmosphere present on the moon. Hence, no scattering takes place on the moon.
Thus, the sky appears dark to the astronauts on the moon.
Thus, statements A and R are both true and R is the correct explanation of A.
