This means that if calcium metal is used in a light meter, the meter will be insensitive to wavelengths longer than those of blue light. Such a light meter would be insensitive to red light, for example. Exercise 1.3. 1
WebPhotoelectric effect: current vs wavelength. In an experiment where the type of metal,intensity of light and potential difference across a battery is kept constant at 2V the … 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.
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.
