Identify a mechanical wave that is also a longitudinal wave

1 answer:

7 0

Mechanical waves, it needs a certain medium to travel through. This medium can be a solid, liquid and gas. There are three types of mechanical waves namely, sound wave, water, and waves through the ropes.

A longitudinal wave is a wave that vibrates in a parallel direction with the motion. Also known as a compression wave. Both mechanical and longitudinal waves produce a sound.

Answer:

But if you place a clear container filled with hydrogen gas between the flashlight and the prism, gaps appear in the smooth rainbow of colors, places where the light literally goes missing. The dark absorption lines of a star at rest (left) get shifted towards red if the star is moving away from Earth (right)

Waves in a fish bowl jostled by the Thingamajigger move to the sides at an average velocity of 0.50 m/s. If they occur once ever

Colt1911 [192]

Answer:

0.125 m

Explanation:

In this problem, we have:

v = 0.50 m/s is the average velocity of the wave

T = 0.25 s is the period of the wave

We can find the frequency of the wave, which is equal to the reciprocal of the period:

$f=\frac{1}{T}=\frac{1}{0.25 s}=4 Hz$

The problem is asking us to find the distance between two crests of the wave: this is equivalent to the wavelength. The wavelength is related to the average velocity and the frequency by the formula:

$\lambda=\frac{v}{f}$
