Question

A tuning fork is vibrating the air around it. What best describes the waves produced by the tuning fork?
A.mechanical, because the air molecules are moving perpendicular to the tuning fork
B.mechanical, because the vibrating tuning fork makes air molecules around it vibrate
C.electromagnetic, because the air molecules are moving parallel to the tuning fork
D.electromagnetic, because the vibrating tuning fork does not need air in order to produce sound

Answer 1

The answer is B on the quiz

Answer 2

Answer: B.mechanical, because the vibrating tuning fork makes air molecules around it vibrate

Explanation:

Mechanical waves require medium to transfer energy. It transfers energy due to vibration of medium particles. The medium it self does not transport. The change in pressure of the medium particles causes transfer of energy through it.

Electromagnetic waves are produced by the electric  field and magnetic field vibrating perpendicular to each other. Electromagnetic waves can travel through space and medium.

A tuning fork vibrates the air around it. The vibrating fork produces mechanical waves.
