Explanation / Answer

a) E = h c / lambda

6.0 * 1.6 * 10-19 = (6.63 * 10-34 * 3 * 108) / lambda

lambda = (6.63 * 10-34 * 3 * 108) / (6.0 * 1.6 * 10-19)

lambda = 207 nm

b) 6.0 eV = 1/2 me v2

v = sqrt [2 * 6.0 * 1.6 * 10-19 / 9.1 * 10-31] = 1.45 * 106 m/s

lambda = h / m v

= (6.63 * 10-34) / (9.1 * 10-31 * 1.45 * 106)

lambda = 0.50 nm
