Answer :
Answer:
Ocean waves and sound waves are mechanical waves.
Explanation:
- Mechanical waves are those waves that needs certain medium for its propagation in any direction.
- Ocean wave cannot travel if there is no channel like water. Similarly sound waves cannot travel in vacuum i.e. it needs medium to propagate. Hence they are mechanical waves.
- Light do not need any form of medium, it can propagate in empty space too. So x-rays, infrared radiation are electromagnetic wave.
