If the When a radiation of wavelength 3000 A° is incident on a metal, stopping potential is found to be 1.85 V and on making radiation of 4000 A° incident on it the stopping potential is found to be 0.82 V, then it has Threshold wavelength of the metal which provide right result to the body and provide better ideas on it and get first class support and solution to make use in a fine manner.
