A ray of light in air is incident
on an air-to-glass boundary at an angle of exactly 30.0° with the
normal. If the index of refraction of the glass is 1.65, what is the
angle of the refracted ray within the glass with respect to the normal?
Carbon tetrachloride (n= 1.46) is
poured into a container made of crown glass (n= 1.52). If a light ray
in the glass is incident on the glass-to-liquid boundary and makes an
angle of 30.0° with the normal, what is the angle of the corresponding
refracted ray with respect to the normal?
An object is placed 20.0 cm from a
thin converging lens along with the axis of the lens. If a real image
forms behind the lens at a distance of 8.00 cm from the lens, what is
the focal length of the lens?
A film projector produces a 1.51 m
image of a horse on a screen. If the projector lens is 4.00 m from the
screen and the size of the horse on the film is 1.07 cm, what is the
magnitude of the magnification of the image?
