Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A sound wave with great amplitude and low frequency will be a ____
A
Soft sound with low pitch
B
Loud sound with low pitch
C
Soft sound with high pitch
D
Loud sound with high pitch
Explanation: 

Detailed explanation-1: -The higher the amplitude of a sound, the louder the sound is. The lower the amplitude of a sound, the quieter the sound is. Therefore, the loud sound produced by a siren has high amplitude whereas the feeble sound produced by a mosquito has low amplitude. Frequency of a sound wave gives the rate of vibration of sound.

Detailed explanation-2: -The pitch of sounds is determined by the frequency of vibration of the sound waves that produce them. Sound waves with a high frequency produce high-pitched noises, whereas sound waves with a low frequency produce low-pitched sounds.

Detailed explanation-3: -Frequency determines the pitch of a sound. Thus if the frequency of vibration is high, the sound has a higher pitch.

Detailed explanation-4: -The pitch of a sound is related to frequency, which is related to the wavelength of a wave. The higher the frequency (shorter wavelength), the higher the pitch. The loudness of a sound wave is related to the amplitude. A bigger amplitude results in a louder sound.

Detailed explanation-5: -A sound wave’s amplitude relates to the change in pressure caused by the wave measured at a specific location. The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases.
