Aband director instructs students to play a pitch louder. how will the sound wave change when the band plays the same pitch louder?

-the speed of the sound wave will increase.
-the frequency of the sound wave will increase.
-the wavelength of the sound wave will increase.
-the amplitude of the sound wave will increase.

me plzz!

The frequency will increase.

The frequency of the sound wave will increase.

Explanation:

A band director instructs students to play a pitch louder. The pitch of sound depends directly on the frequency of the sound wave. Frequency of a sound wave is defined as the number of oscillation or vibrations per second. It is measured in hertz (Hz).

So, the frequency of the sound wave will increase when the band plays the same pitch louder. So, the correct option is (b).

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
