Practice Problems on Mirror Equation

Problem 1: An object is placed 15 cm in front of a concave mirror with a focal length of 10 cm. Determine the image distance and state whether the image is real or virtual.

Problem 2: A convex mirror has a focal length of -20 cm. If an object is placed 30 cm in front of the mirror, find the image distance and describe the nature of the image.

Problem 3: A concave mirror has a radius of curvature of 30 cm. Calculate the focal length of the mirror and determine the image distance when an object is placed 20 cm in front of it.

Problem 4: An object is positioned 12 cm in front of a concave mirror with a focal length of 8 cm. Calculate the magnification of the image.

Problem 5: A concave mirror has a radius of curvature of 40 cm. If an object is placed at a distance of 60 cm from the mirror, determine the image distance and whether the image is magnified or diminished.

Problem 6: A convex mirror has a focal length of 30 cm. If an object is positioned 40 cm in front of the mirror, calculate the image distance and describe the characteristics of the image.

Mirror Equation in Physics is the equation for mirrors that provides the relation between the distance of the object and the image, as well as its focal length. Mirror Equation is helpful in determining object position, image position or focal length given that two of the parameters are given. In optics, which is the branch of science that deals with the study of light and its interactions with various materials and optical elements, mirrors are used in various instruments for various purposes. Thus, understanding the relationship between the focal length of the mirror and the distance between the object and the image from the mirror is very important.

In this article, we will explore the concept of the Mirror Equation in detail, Mirror Equation Proof, and Mirror Equation for Magnification with various types of mirrors as well. So, let’s start learning about the concept of Mirror Equations.
