Frequency of a wave depends on its amplitude.
Name the characteristic of sound which depends on : (a) amplitude (b) frequency.
Write true or false for each statement:
(a) When sound propagates in air,it does not carry energy with it.
(b) In a longitudinal wave,compression and rarefaction are formed.
(c) The distance from one compression to nearest rarefaction is called wavelength.
(d) The frequency is measured in second.
(e) The quality of sound depends on the amplitude of wave..
(f) The pitch of sound depends on frequency..
(g) Decibel is the unit of pitch of a sound.
State the numerical value of the frequency of oscillation of a second's pendulum. Does it depend on the amplitude of oscillation?
