Lesson: Reflected ImagesPhysics
In this lesson, we will learn how to explain the formation of images by focusing light rays in mirrors that have different radii of curvature.
Sample Question Videos
What is the focal length of a makeup mirror that produces a magnification of 1.50 when a person’s face is 12.0 cm away?
A light bulb is placed between a plane mirror and a convex mirror that has a radius of curvature of 8.0 cm. The distance from the plane mirror to the vertex of the convex mirror is 30 cm, along the mirror’s optical axis. The plane mirror is located 10 cm from the bulb, also along the convex mirror’s optical axis. The system forms multiple images.
Find the distance from the vertex of the convex mirror to the first image that produced by the convex mirror.
Find the position of the second image formed by the convex mirror.
An electric room heater uses a concave mirror to reflect infrared radiation from hot coils. The mirror in a heater has a radius of curvature of 50.0 cm and produces an image of the coils 3.00 m away from the mirror. How far from the curved mirror are the coils located?
