The frequency of a wave traveling through the air of a hot, dry desert is 1,200 hertz. its wavelength is 0.300 meters. what is the speed of the wave? a. 360 meters/second b. 40.2 meters/second c. 0.25 meters/second d. 120 meters/second

the answer to this problem is A

The speed of the wave is 360 m/s.

A is correct.

Explanation:

Given that,

Frequency f = 1200 hertz

Wave length = 0.300 m

The velocity of light is the product of the frequency and the wavelength.

Frequency is the inverse of the time period.

Wave length is the distance between two identical point in the wave.

Formula of the velocity of the light is defined as,

Where, v = velocity of light

f = frequency

= wavelength

Put the value into the formula

Hence, The speed of the wave is 360 m/s.

Yes, it is possible to change the transitional kinetic energy of an object without changing its rotational energy. For example dropping a spinning ball into the side of the table, the ball will keep its rotational motion while its transitional kinetic energy is changing.
