According to the law of refraction, n 2 sin θ 2 = n 1 sin 1 . We take n 1 = 1 and n 2 = 1.33 (from Table 33-1). Then, 2 1 1 2 1 350 133 2555 = F H G I K J = ° F H G I K J −− sin . . .. n L is given by L = = °= A 22 150 072 tan ( . . m) tan25.55 m. The length of the shadow is 0.35 m + 0.72 m = 1.07 m. 51. Consider a ray that grazes the top of the pole, as shown in the diagram that follows.
