WebFeb 9, 2024 · According to the equation of photoelectric effect equation we have; \(\frac{hc}{λ}\) = ϕ + eV s -----(1) Here we have h is Planck's constant, c is the velocity of light, λ is the wavelength, ϕ is the work function and V s is the stopping potential. CALCULATION: Given: Wavelength, λ 1 = 491 nm. Stopping potential, V s1 = 0.710 V WebEinstein’s photoelectric effect is caused when the photons resent in the light interact with the electrons in the metal Each of the photons interacts with 1 electron. The energy of the incident photon is used in releasing the electrons from the surface and to transmit energy to the ejected electrons.
