A student notices that the image produced from a large concave mirror of a distant skyscraper (h = 72 m) is inverted and the magnitude of the height is |hi| = 0.89 m tall. The image is located d = 157 cm in front of the mirror. a) Write an expression for the distance between the mirror and the skyscraper, ds. b) Numerically, what is the distance in meters? c) Numerically, what is the focal length of the mirror, f, in cm?
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.
