Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
An observer to the right of the mirror–lens combination
shown in Figure P23.62 sees two real images that are the same
size and in the same location. One image is upright, and the
other is inverted. Both images are 1.50 times larger than the
object. The lens has a focal length of 10.0 cm. The lens and
mirror are separated by 40.0 cm. Determine the focal length
of the mirror. (Don’t assume the figure is drawn to scale.)
