प्रश्न
Which of the following is a mechanical wave?
विकल्प
Radio waves
X-rays
Light waves
Sound waves.
उत्तर
Sound waves
There are mainly two types of waves: first is electromagnetic wave, which does not require any medium to travel, and the second is the mechanical wave, which requires a medium to travel. Sound requires medium to travel, hence it is a mechanical wave.
