Question

calculate the energy associated with a wave of wavelength 1m​

Answer 1

Another form of Planck's equation uses the simple relationship that c = λ f, where λ is the wavelength of the photon, and c is the speed of light, which is a constant and is 2.998 × 108 m/s. If you know the frequency of the photon, you can easily calculate the wavelength by the following formula: λ = c / f.
