Question

Calculate the frequency of monochromatic light of wavelength  = 550 nm in a vacuum. What color is it?q

b) Calculate the frequency, wavelength, and speed of this light inside a lens composed of glass having index of refraction n = 1.58.

2) A ray of light (in air) enters the top of a glass plate at an angle of 35 from a line perpendicular to the surface. The refractive index of the glass is 1.48.

a) Calculate the angle between the ray path and the line perpendicular to the surface as it travels through the glass.

b) After exiting the bottom of the plate, how does the ray path compare to that entering the top?

c) draw the ray paths showing the light entering the glass plate, as it travels through the plate, and after it exits the plate

3) For light traveling from an incident medium having n = 1.33 into a substance with n = 1.64, calculate the angle between the refracted ray and a line perpendicular to the surface if the incident angle is

a) 30 degrees and b) 45degrees (angles measured between the ray and a line perpendicular to the surface). c) for light exiting the medium (n = 1.64) into air (n = 1.00), what is the critical angle for total internal reflection?

4) On a separate sheet, sketch and label the following sections through a uniaxial positive indicatrix, including privileged (vibration) directions and associated refractive indices. The sketches do not need to be precisely to scale, but should be qualitatively correct with respect to the relative lengths of the axes:

a. A principal section; b. A random section: c. A circular section:
