The Photoelectric Effect Cesium metal was used as an electrode in a photoelectric experiment, A specially designed light source ( from which various frequencies of light could be obtained using filters) produced photoelectrons of various energies. The data obtained is shown below. 2. 405 units = X-axis york's how offT E 1 79 units Frequency of Incident light Maximum energy of emitted ( in 10 # Hz) photoelectrons (ineV) axtb 6.00 0:700 = 1.12 x10 75 dow 8.00 1.40 = 2. 24 x10. 73 10.0 - 14- 1 16 , 2 2.20 = 3.5 2XID ds X , 12.0 7 3.10 12, 12 33 X214.0 47 3.90 = 6,24 X10 5 1.

From the graph, find the x and y intercepts, and the slope. Express your slope in joule-seconds (J-s). Compare this value to planck's constant from your data table
