Eedhe Example 19 How ted per second ample 19 How many photons are green about ofved on earth per cm per hour if the energy am the sun reaching on the earth is at the rate (i) vi cal cm-2 min and average wavelength of colo solar light be taken as 5500 Å. (Tak Use h = 6-6 x 10-34 J, c = 3 x 108 ms -1 and 1 cal = 42 J. 5500 Å - 5500 x 10-10 m Isee)
