A concave mirror forms an image of $20 \mathrm{~cm}$ high object on a screen placed $5 \cdot 0 \mathrm{~m}$ away from the mirror. The height of the image is $50 \mathrm{~cm}$. Find the focal length of the mirror and the distance between the mirror and the object.

Key Concepts

Concave Mirror Properties

Concave mirrors are curved inward, meaning that they converge parallel rays of light to a focal point. They form real or virtual images depending on the object's position relative to the focal point. Their geometry is governed by the mirror curvature and the focal length, which is a fundamental parameter in analyzing image formation in optical systems.

Mirror Equation

The mirror equation, given by 1/f = 1/u + 1/v, relates the focal length of the mirror (f) to the object distance (u) and the image distance (v). This equation is essential for calculating unknown parameters in mirror setups, and by following proper sign conventions, it enables the analysis of real and virtual image formations.

Magnification

Magnification in mirror systems describes the ratio of the image height to the object height and is also related to the distances of the object and image from the mirror by the formula m = -v/u. It provides insight into the size and orientation of the image, and is instrumental in solving problems where the height of the image relative to the object height is given.
