Formula of threshold wavelength
WebSep 7, 2024 · What is the formula for threshold wavelength? 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). WebIf the wavelength of incident light is 260nm, the maximum kinetic energy electrons will be: Given E(ineV)= 1237 λ(innm) Q. Solve this: Q6. Define the term 'threshold frequency' in relation to photoelectric effect. (Fogeign 2011) Q. With reference to photoelectron effect, define threshold wavelength.
