Question

relation between threshold frequency, wavelength and work function​

Answer 1

Answer:

The frequency of the light for which its energy is equal to the work function is called threshold frequency ν0. Therefore, ϕ=hν0. Let us use the relation between the frequency and the wavelength of light, i.e. ν=cλ. When the light wave has threshold frequency, its wavelength is called threshold wavelength (λ0).
