Answer:
The relation between f,T,λ
 f=
 λ =
 λ =
Explanation:
Let us consider,
                           wavelength as λ
                              frequency as  f
                              time period as T
The <em>time period</em> is defined as time taken by the wave to complete one oscillation or number or seconds to complete one full oscillation.
The <em>frequency </em>is defined as number of oscillation done per second.
The <em>wavelength</em> is defined as distance between two successive crests or trough. in a wave.
<em>The frequency and time period are reciprocals. </em>
<em>The wavelength and frequency are reciprocals ie larger the wavelength shorter is the frequency</em>
The relation between frequency and time period is f = .
.
The relation between wavelength and frequency is λ =
                      where v is velocity of light.
The relation between wavelength and time period is λ =
