A diver in a swimming pool shines a flashlight up from below the water%u2019s surface at an angle of 30.0 degrees from the normal. (assume n = 1.33 for water, 1.00 for air)
a. at what angle to the normal does the light leave the water?
b. what is the minimum incident angle from the normal for which the light will be totally reflected from the surface and remain within the pool?
