Question

Can we think of any relation between the Pitch and the Time period of a sound wave?

A: Greater the time period, higher the pitch
B: Greater the time period, lower the pitch
C: No effect of the variation, pitch will remain same
D: A relation cannot be established
this is a mcq

Answer 1

Answer:

and the Decibel Scale

The Speed of Sound

The Human Ear

A sound wave, like any other wave, is introduced into a medium by a vibrating object. The vibrating object is the source of the disturbance that moves through the medium. The vibrating object that creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker. Regardless of what vibrating object is creating the sound wave, the particles of the medium through which the sound moves is vibrating in a back and forth motion at a given frequency. The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. If a particle of air undergoes 1000 longitudinal vibrations in 2 seconds, then the frequency of the wave would be 500 vibrations per second. A commonly used unit for frequency is the Hertz (abbreviated Hz), where

Answer 2

Answer:

The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low.

Explanation:

These differences in the pitch of the sound are caused by different spacing in the waves; the closer together the waves are, the higher the tone sounds.
