A laser beam is incident at an angle of 41.0° to the vertical onto a solution of corn syrup in water.
(a) If the beam is refracted to 20.84° to the vertical, what is the index of refraction of the syrup solution?
(b) Suppose the light is red, with wavelength 632.8 nm in a vacuum. Find its wavelength in the solution.
(c) What is its frequencyin the solution?
(d) What is its speed in the solution?
