(a) Explanation The given figure is shown below. Figure (1) In triangle AOB, tan θ = x L 2 x = L 2 tan θ In triangle AOB, cos θ = L 2 ( L 2 ) 2 + x 2 The expression for speed of light is, v = d x d t Substitute L 2 tan θ for x above equation and differentiate, v = d ( L 2 tan θ ) d t v = L 2 (b) To determine The value of x corresponding to the minimum value of speed. (c) To determine The minimum value for speed. (d) To determine The maximum speed of the spot on the wall. (e) To determine The time interval in which the spot changes from its minimum to maximum speed.
