Question

What is characteristic of both sound waves and

electromagnetic waves?
(1) They require a medium.
(2) They transfer energy.
(3) They are mechanical waves.
(4) They are longitudinal waves.

Answer 1

The characteristic of both sound waves and electromagnetic waves are:

(2) They transfer energy.

Step-by-step explanation:

A wave may be a longitudinal wave whereas, magnetic force waves are transverse waves. Sound may be a mechanical vibration that passes through a medium like gas, liquid or solid to become a sound. Whereas,Electromagnetic waves, additionally called EM wave, is that the travel path of electromagnetic wave or EMR.

Answer 2

"(2) They transfer energy" is the best option from the list regarding the characteristics of both sound waves and electromagnetic waves, but these energies are different.
