Here,
t is time period.
F is frequency.
v is velocity of wave. (v = 3 x 10^8 ms-1 )
t = 2 x 10^-10 s
F = 1/t
F = 1/(2 x 10^-10)
F= 10^10/2
F = 10 x 10^9 /2
F= 5 x 10^9 Hz
Hence, frequency is 5 x 10^9 Hz.
v= F λ
3 x 10^8 = 5 x 10^9 x λ
3/5 x 10^(8-9) = λ
λ = 0.6 x 10^-1
λ = 0.6/10
λ = 0.06 m
Hence, the wavelength is 0.06 metres or 6 centimetres.
