use formula
speed =wavelength x frequency
3 x 10^8 = 420.5 x frequency
frequency =3 x 10^8/420.5
=0.0071 x 10^8 Hz
=710000 Hz
speed =wavelength x frequency
3 x 10^8 = 420.5 x frequency
frequency =3 x 10^8/420.5
=0.0071 x 10^8 Hz
=710000 Hz

Wavelength , λ = 420.5 m
Speed , v = 3 × 10⁸ m /s
Frequency = ν
speed , v = λν
Frequency , ν = v ÷ λ
= 3 × 10⁸ m /s ÷ 420.5 m
= 710000 Hz
Speed , v = 3 × 10⁸ m /s
Frequency = ν
speed , v = λν
Frequency , ν = v ÷ λ
= 3 × 10⁸ m /s ÷ 420.5 m
= 710000 Hz
