Side-view mirrors allow a driver to see what is directly behind the vehicle. The driver is not located in the center of the vehicle, so the left- and right-side mirrors must be oriented at different angles. Imagine a line that runs through both side-view mirrors. The driver’s eyes are located a distance y = 19 inches behind this line. The distance from the driver’s eyes to the center of the left mirror is dL = 25 inches and the distance from the driver’s eyes to the center of the right mirror is dR = 49 inches. Refer to the figure. Assume that the driver’s eyes and both mirrors lie in the same horizontal plane. Find the angle, θL, of the left mirror, in degrees. Find the angle, θR, of the left mirror, in degrees.
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.
