WebIn a photoelectric experiment it is found that a stopping potential of 1.00 V is needed to stop all the electrons when incident light of wavelength 229 nm is used and 1.6 V is needed for light of wavelength 207 nm. From these data determine Planck's constant. WebWhen photons of wavelength λ 1 are incident on an isolated sphere, the corresponding stopping potential is found to be V. When photons of wavelength λ 2 are used, the corresponding stopping potential was thrice that of the above value. If light of wavelength λ 3 is used then find the stopping potential for this case:
WebJan 30, 2024 · The wavelength is defined as the distance between two peaks of the electric field with the same vector. The frequency of a photon is defined as how many wavelengths a photon propagates each second. Unlike an electromagnetic wave, a photon cannot actually be of a color. Instead, a photon will correspond to light of a given color.
