1. Asri did a photoelectric effect experiment using aluminium as the anode. The work function of aluminium is 4.08 eV. X-rays 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 X-rays with same intensity but different wavelengths. (iii) repeat his experiment with incident X-rays with same wavelength but different intensities. (c) Sketch a graph showing the variation o

well 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?
