Question

A ray of light with a wavelength of lambda=600 nm travels through air (n=1.000293) and strikes a flat block of glass (n=1.50) of thickness 2.00 cm at an angle of 30.0 degrees with the normal.

(a) Trace the light beam through the glass and find the angle of incidence (i) and refraction (r) at the surface where the light enters the glass

(b) Perform the same calculation as above for the surface where the light exits the glass.

(c) Calculate the amount of time it takes for the light to pass through the glass along its path. Give your answer to a reasonable precision using exact values for necessary quantities and don't round intermediate results.

(d) calculate the wavelength of the light in the glass.
