A laser beam is incident at an angle of 29.4° to the
vertical onto a solution of corn syrup in water.
(a) If the beam is refracted to 18.50° 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.
nm

(c) Find its frequency in the solution.
Hz

(d) Find its speed in the solution.
m/s
