- As shown a laser beam deflected by a 30°-60°-90° prism. What is the prism’s index of refraction?Light is incident from air onto the surface of a liquid. The angle of incidence is 47.0°, and the angle of refraction is 36.0°. At what angle of incidence would the reflected light be 100% polarized? Number Incident light Liquid i Reflected light Refracted light UnitsLight enters a container of liquid at an angle of 49° to the normal; the refracted beam makes an angle of 29° with the normal. Calculate the index of refraction of this liquid. Group of answer choices 1.96 1.44 1.56 1.78
- What causes the refraction of light at a boundary between two media? A An angle of incidence greater than the critical angle The absorption and emission of light back into the original medium The different indices of refraction for different wavelengths in the same medium Different speeds of light in the two mediaAs a ray of light travels through a medium with wavelength and speed v = f x , the refractive index (n) of that medium may be expressed as (where fo and o are the frequency & wavelength in free space) Group of answer choices o / x o f/ fo / oA thin beam of light makes an angle of 60° with the surface (not the normal) of a body of water (n = 1.33). Once the light beam refracts into the water what angle does the beam make with the surface of water? 30° 68° 22° 60°
