Value: 2 The variable er 4/1 o square represents the speed of light. C < Prev n gtTotal internal reflection can occur when light travels from a material with a low index of refraction to a materia I with a high index of refraction. True FalseCalculate the angle of refraction for a light ray if medium 1 has a refractive index of 1.2, medium 2 has a refractive index of 1.8 and the angle of incidence is 44.43^circ a. 27.8^circ b. 44.43^circ C. 29.6^circ d. 0.49^circWhen a light ray passes from one medium to another, its speed and wavelength change, but its frequency does not. True FalseA ray of light is incident through glass, with a refractive index of 1.52, on an interface separating glass and water with a refractive index of 1.32. What is the angle of refraction if the angle of incidence of the ray in glass is 25^circPREV 153154155156157158159160161 NEXT
