Question

3. 3/4 points | Previous Answers SerCP11 22.P011 MI. Miy Notes Ask Your Teacher A laser beam is incident at an angle of 30.8 to the vertical onto a solution of corn syrup in water (a) If the beam is refracted to 19.020 to the vertical, what is the index of refraction of the syrup solution? 1.57 (b) Suppose the light is red, with wavelength 632.8 nm in a vacuum. Find its wavelength in the solution. 403 (c) Find its frequency in the solution. 7.44e14 Your response differs from the correct answer by more than 10%. Double check your calculations. Hz (d) Find its speed in the solution. 1.9e8 m/s

Explanation / Answer

c) Frequency remains constant, irrespective of the medium.

So from f=v/lambda,

f= 3x10^8/ 632.8x10^-9

= 4.74x10^14 Hz
