Question

Choose the correct nature of waves which enables us to see the solar flares but not hear them.

• A. Sound: mechanical wave
  Light: non-mechanical wave
• B. Sound: non-mechanical wave
  Light: mechanical wave
• C. Sound: mechanical wave
  Light: mechanical wave
• D. Sound: non-mechanical wave
  Light: non-mechanical wave

Answer 1

The correct option is A Sound: mechanical wave

Light: non-mechanical wave
We can see the solar flares but cannot hear them because sound wave is mechanical in nature and requires a material medium for propagation

Light on the other hand is a non-mechanical wave, which does not require any material medium for its propagation and can travel through the vacuum in space.
