Subject: (Reflection, Refraction and Flat Mirrors)

I need help witht he steps, calculation and explination, but if you can can you translated it in spanish if you can't i dont have a problem

a) If a ray of light propagates from air to water and the incident ray is 60 with respect to the normal surface separating both media, what is the angle of the reflected ray and the angle of the refracted (transmitted) ray? (naire = 1.0002926, nagua = 1.333)

b) If a light ray propagates from ice to polycarbonate and the refracted (transmitted) ray is 25 with respect to the normal surface separating both media, what is the angle of the incident ray and the angle of the reflected ray? (nhielo = 1.309, npolycarbonate = 1.585)

c) If a light ray propagates from Teflon to an unknown medium with an incident ray at 55 with respect to the surface normal and the refracted (transmitted) ray is at 35 with respect to the surface normal separating both media, what is the refractive index of the unknown medium? (nteflon = 1.36)

d) If a ray of light propagates from an unknown medium into quartz with an incident ray at 10 with respect to the surface normal and the refracted (transmitted) ray is at 25 with respect to the surface normal separating both media, what is the refractive index of the unknown medium? (nquartz = 1.544)

e) What is the critical angle for a propagation of light from silicon to air? Say and explain whether or not there is total internal reflection if the incident light beam is at an angle of 40. (nsilicon = 4.01, naire = 1.0002926)

f) How many images are formed if two flat mirrors are placed at a 90 angle?

g) How many images are formed if two flat mirrors are placed at a 60 angle?

h) What would be the distance of the image from a flat mirror if the object is placed 0.5 meters from the flat mirror?
