Concept explainers

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.

Question

A product designer wishes to specify the properties of a concave makeup mirror, which is supposed to provide an upright and enlarged image of the user's face. The designer wants a
magnification factor of two, and he assumes that the user's face will be 20 cm in front of the mirror.
What radius of curvature should be specified (in m) for the fabrication of these mirrors?
Enter a number.
"definition of magnification to derive the image location. Next, use the mirror equation to obtain the radius of curvature from the respective locations of the object and image.
Pay close attention to sign conventions and double check your arithmetic. Bear in mind the relationship between radius of curvature and focal length. m
