1. Asri did a photoelectric effect experiment using aluminium as the anode. The work function of aluminium is 4.08 eV. Xrays have wavelengths between 10  0.01 nm.
(a) What is meant by the phrase ‘work function of aluminium’?
(b) With the aid of a graph (if necessary), explain Asri’s experimental observations and conclusion when he uses
(i) a red incident light of wavelength 650 nm.
(ii) incident Xrays with same intensity but different wavelengths.
(iii) repeat his experiment with incident Xrays with same wavelength but different intensities.
(c) Sketch a graph showing the variation o

Best ResponseYou've already chosen the best response.1well then.. you need to go through your text book and study about this.. before trying to attempt to solve this problem .. do you know what photons are ? and what is the expression for energy of an photon?
