1. A potassium vapor sign consists of K atoms which give off violet light (I = 425.4 nm). a. Calculate the frequency for this wavelength. b. Calculate the JE when only one atom gives off light and when 0.333 moles of atoms give off light simultaneously. (c = 2.9979 x 10° m/s, h = 6.626 x 10-34 J*s) [7.047 x 104 hz] [4.670 x 10-19 J] [93.6 kJ]
