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.

Explanation :

Loudness is defined as how our ear perceives the sound. It is basically related to the intensity of a sound wave.

When the same pitch is played louder, its amplitude changes. Amplitude is the maximum displacement covered by a wave.

This is the only difference between the loudness to that of shrillness. The amplitude of the loud sound is more as compared to that of shrill sound.

So, the correct option is (d).

answer; /// the above statement is (true);
