A laser beam is incident at an angle of 33.0° to the vertical onto a solution of cornsyrup in water.(a) If the beam is refracted
to 24.84° to the vertical, what is the index ofrefraction 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?
