A wave in slinky travelled to and fro in 5 sec the length of the slinky is 5 m. The velocity of wave is
Loud sound can travel a larger distance, due to
Which characteristic is this? We can distinguish between sound having the same pitch and loudness.
Speed of sound depends upon
Speed (v), wavelength (λ) and frequency (ν) of sound are related as
The time taken by the wave for one complete oscillation of the density or pressure of the medium is called the time period, T. The speed v, frequency ν, and wavelength λ, of sound are related by the equation, v = λν.
To hear a distinct echo the time interval between the original sound and the reflected sound must be
Reverberation of sound is used in
Children under the age of 5 can hear upto
Dolphins, bats and porpoise use
The part of human ear that converts sound vibrations into electrical signals are
