The critical angle for an air-glass interface is  29.2°. When a light ray in air is incident on the interface, the reflected ray is 100% polarized. What is the angle of refraction of that ray in degrees?  (numerical answer only with 3 sig figs please)

The critical angle for an air-glass interface is  29.4°. When a light ray in air is incident on the interface, the reflected ray is 100% polarized. What is the angle of refraction of that ray in degrees?  (numerical answer only with 3 sig figs please)

The index of refraction for red light in water is 1.331, and that for blue light is 1.340. If a ray of white light enters the water at an angle of incidence of 78.40°, what are the underwater angles of refraction for the blue and red components of the light?

Refractive Index (n) is a ratio of the speed of light in a vacuum to the speed of light in materials such as glass, water, plastic, etc. Using Snell's Law, and given an air to glass interface with and angle of incidence of 15 degrees, what will be the angle of refractance R if the refractive index of the glass is 1.5 ? Snell's Law: n; (sin I) = n, (sin R) So, Sin R = n; (sin I) / n And, R = arcsin (n; (sin I) / n,) For each angle I, find angle R: 5. I=0, R = 6. I=45, R = 7. I= 60, R = 8. I = 75, R = = arcsin (1(.259)/1.5) = arcsin (.172) = 9.9 degrees Wavelength in Air- Light- Angle of Light -Wavelength in Glass Normal 90° R Air nj-1 Glass
