Explanation:
A = Wavelength
The distance between two consecutive crest or trough is wavelength
B = Amplitude
The maximum distance covered by the particles of a wave
C = Rest postion/equilibrium
When there is no disturbance in the medium
D = Trough
It is the displacement in negative direction
E = Crest
It is the displacement in positive direction
(A) The relationship between the wavelength and frequency is given by :
There is an inverse relationship between wavelength and frequency.
(B)
When the frequency is decreased, the wavelength of a wave increases.
