A prism is surrounded by air. A vertical ray of light exits a prism that is a right, isosceles triangle as shown in the picture below. The prism is made of glass with a refractive index 1.6. What is the value of the incident angle 0 that the light makes with the normal to the bottom surface that would allow a vertical ray to leave the beam? 45° 45° Provide your answer in degrees, use three significant figures in your calculation.
