Explanation 1) Concept: We can apply Snell’slaw to find out the angle of refraction as the speed of incident and refracted wave is given. By applying definition of refractive index, we will get the ratio of speeds, and finally, we can find out the angle of refraction. 2) Formula: i) Index of refraction n = c v where c is speed of light in vacume and v is speed of light in medium ii) Snell’s law n 2 s i n θ 2 = n 1 s i n θ 1 3) Given: i) Angle of incidence θ 1 = 30 ° ii) v d = 4.0 m / s , speed of deep water wave iii) v s = 3.0 m / s , speed of shallow water wave 4) Calculations: a) We know that n 1 = c / v d and n 2 = c / v s Take ratio of n 1 and n 2 ; we get n 1 n 2

A bungee jumper plans to bungee jump from a bridge 64.0 m above the ground. He plans to use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 6.00 m above the water. Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge. (a) What length of cord should he use? Use subscripts 1 and 2 respectively to represent the 5.00 m test length and the actual jump length. Use Hooke's law F = KAL and the fact that the change in length AL for a given force is proportional the length L (AL = CL), to determine the force constant for the test case and for the jump case. Use conservation of mechanical energy to determine the length of the rope. m (b) What maximum acceleration will he…
