Question

A laser beam is incident at an angle of 44.0 degree from the vertical onto a solution of corn syrup in water. The beam is refracted to 26.44 degree from the vertical. What is the index of refraction of the corn syrup solution? Assume that the light is red, with vacuum wavelength 632.8 nm. Find its wavelength in the solution. nm Find its frequency in the solution? Hz Find its speed in the solution? m/s Find the speed of light in each of the following materials. cubic zirconia Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, m/s crown glass m/s benzene m/s

Explanation / Answer

a) sin(i)/sin(r) = n
n = 1.56
b) lambda' = lambda/n = 405.61 nm
c) fRequency in sol = frequency in vaccum = c/lambda = 0.474*10^15 Hz
d) speed in soln = c/n = 1.923*10^8 m/s

a) c' = c/2.176 = 1.378*10^8 m/s
b) c' = c/1.52 = 1.973*10^8 m/s
c) c' = c/1.501 = 1.9986 *10^8 m/s
