Question

If amplitude and frequency of sound wave are increased which of the following is true?
a) Loudness increase and pitch is higher
b)Loudness increase and pitch is unchanged
c)Loudness increase and pitch is lower
d)Loudness decrease and pitch is lower​

Answer 1

Answer:

a) Loudness increase and pitch is higher.

Explanation:

The wavelength is inversely proportional to the frequency, the wavelength will decrease when the frequency increases, resulting in higher tones. The amplitude is perceived as the loudness of sound.

Answer 2

Answer:

a) Loudness increase and pitch is higher.

Explanation:

• Because the wavelength is inversely related to the frequency, as the frequency rises, the wavelength decreases, resulting in higher tones. The loudness of a sound is measured by its amplitude.
• By the sound's loudness we get the amplitude. The loudness of a sound diminishes as its amplitude decreases.
• In addition, the frequency of sound affects the pitch of the sound. The pitch of sound drops as the frequency of sound lowers.
• To put it another way, the shrillness of sound will be reduced.
