Sound produced by a tining fork is a sort of :-

A

digital signal

B

analog signal

C

both (A) and (B)

D

neither (A) nor (B)

Text Solution

Verified by Experts

The correct Answer is:
B
The continuous variation in density of air w.r.t. time surrounding the tuning fork due to vibrating fork is analogous to the variation of voltage w.r.t. time in an analog signal.

When the beats are produced by vibration of two tunning forks of nearly equal frequencies then the velocity of propagation of beats

Fill in the blanks with appropriate words and write the complete statements: Sound produced by vibrations of a simple pendulum is ………….sound.

Questions based on paragraph : Sound is propagated in a material medium in the form of compression and rarefactions. One compression and one rarefaction together form one cycle of the sound wave. The number of cycles produced per second is called as frequency. A tuning fork is a two-pronged device which vibrates to produce sound when struck. The frequency of a tuning fork is decided by the dimensions of the prong and the material used for making the fork. When these sound waves reach ears of listener, his ear-drum vibrates. Accordingly specific signals are conveyed to the brain and the listener gets a sense of hearing sound. : Will two tuning forks of same dimensions but different material produce same type of sound when struck with the same force?
