1-Use Snell's law to find the angle that a beam of light makes with the normal to a class surface, entering from air with angle 44 in degrees, after it refracts and is traveling inside the glass. Assume the index of refraction is 1.5

2-

Snell's law describes the relationship betwee the angle a light ray makes as it leaves a surface, the angle it makes incident on the surface. and the indices of refraction on both SldeS of the surface. lf light incident in air at angle of 30 degrees from the normal onto glass With an index of refraction of1.5 .. PICK these answers that apply [1 There is light reflected back into the air from the surface C] The angle is too steep for light to retract and it is all reected. C] The light in3ide the glass is closer to the normal, makes a bigger angle With the surface, than the inCIdent light [3 Inside the material the light leaving the surface is closer to the surface. makes a bigger angle with the normal. than the entering light makes in air
