Question

Choose the correct statements (s) from the following?

• A. Mechanical waves need medium for their propogation
• B. Sound cannot travel through vaccum
• C. Mechanical waves transport energy from one place to another
• D. Sound waves are non mechanical waves

Answer 1

Answer: (A), (B), (C)

The correct options are
A Mechanical waves need medium for their propogation
B Sound cannot travel through vaccum
C Mechanical waves transport energy from one place to another

A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sounds waves are incapable of travelling through a vacuum as no matter for the vibrations to work in.
