A narrow beam of white light is incident on a 5-cm-thick plate of glass, at an angle of 60 degrees. The index of refraction of the glass is 1.513 for red light and 1.535 for violet light. The light is dispersed into constituent colors and emerges from the other side. (0) Which emerging ray is which color (red or violet)? (b) Calculate the width of the emerging beam (as shown). (c) You wish to reduce the intensity of the beam reflecting off the top surface with a linear polarizer. Draw a diagram illustrating the direction of the polarization axis
