Solution 1 E = h, Multiply this value by the Avogadro constant to find the energy of a mole of photons (where the Avogadro constant, NA, is the number of entities in a mole. E = h, to calculate the energy of one photon where h, the Planck constant = 6.626  10–34 J s  = 1.00  1011 Hz (s–1) E = (6.626  10–34 J s)  (1.00  1011 s–1) E = 6.63  10–23 J The value for a single photon can then be converted into the energy for one mole of photons by multiplying by the Avogadro constant, 6.022  1023 mol–1

1.2 Light Interference A set of maxima and minima in an interference pattern suggests a totally different effect. As shown in Figures 3.7 and 3.8 (p.114), this experiment is demonstrating the wave like properties of light, where the interference pattern is generated from individual waves adding together (in phase) or subtracting from one another (out of phase).
