The figure shows a refracted light beam in linseed oil making an angle of ? = 15.8° with the normal line NN'. The index of refraction of linseed oil is 1.48. a) Determine the angle ?. b) Determine the angle ?'.

. A plastic-coated window consists of Perspex and glass. At the Perspex to glassinterface the angle of refraction is 30.00. and the angle of incidence is 20.00. Ifthe refractive index of the glass is 1.75, what is the refractive index of thePerspex?

Rays of the Sun are seen to make a 33.0​∘ angle to the vertical beneath the water. At what angle above the horizon is the Sun?

A point source of light is submerged 2.30 m below the surface of a lake and emits rays in all directions. On the surface of the lake, directly above the source, the area illuminated is a circle. What is the maximum radius that this circle could have?

A student stands dsub0=2.4 m in front of a floor-to-ceiling mirror. Her eyes are hsube=1.53 m above the floor and she holds a flashlight at a distance hsubf=.55 m above the floor. Calculate the angle in degrees that the flashlight makes with respect to the floor if the light is reflected into her eyes.
