12. Waves of frequency 150 Hz are produced in a string. Find the
(a) wavelength, (b) amplitude and (c) velocity of the waves in SI units.
Dear Student,
1) The wavelength is the distance between adjacent identical parts of a wave, parallel to the direction of propagation.
So wavelength = 25cm
2) Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position, so amplitude = 6cm
3)The wave velocity is the speed at which the disturbance moves.
velocity = wavelength x frequency
= 25 x 150
= 3750cm/sec
