A convex security mirror has a radius of curvature of -1.50 m. (a) A shoplifter picks up a 0.255-mhigh purse 11.5 m from the mirror. How far behind the mirror is the image of the purse? (b) Is the image real or virtual? (c) How high is the image of the purse? (d) Are convex security mirrors better for viewing detailed images or large fields of view?
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.
A convex security mirror has a radius of curvature of -1.50 m. (a) A shoplifter picks up a
0.255-mhigh purse 11.5 m from the mirror. How far behind the mirror is the image of the
purse? (b) Is the image real or virtual? (c) How high is the image of the purse? (d) Are
convex security mirrors better for viewing detailed images or large fields of view?
