A tuning fork vibrates at a frequency of 512 hertz
when struck with a rubber hammer. The sound
produced by the tuning fork will travel through
the air as a
(1) longitudinal wave with air molecules
vibrating parallel to the direction of travel
(2) transverse wave with air molecules vibrating
parallel to the direction of travel
(3) longitudinal wave with air molecules vibrating
perpendicular to the direction of travel
(4) transverse wave with air molecules vibrating
perpendicular to the direction of travel

Sagot :

The sound produced by the tuning fork will travel through
the air as a (1) longitudinal wave with air molecules vibrating parallel to the direction of travel.

Answer: The correct answer is " longitudinal wave with air molecules

vibrating parallel to the direction of travel".

Explanation:

In longitudinal wave, the particles vibrate parallel to the direction to the propagation of the wave. For example, sound wave is a longitudinal wave.

It needs a medium for its propagation. It can travel in solid, liquid and gas. It travel faster in solid in comparison to the liquid.

In the given problem, a tuning fork vibrates at a frequency of 512 hertz  when struck with a rubber hammer. The sound  produced by the tuning fork will travel through air. Here, a longitudinal wave with air molecules vibrating parallel to the direction of travel.

Therefore, the correct option is (1).
