Magnification Calculations

These flashcards cover key concepts related to magnification calculations, essential for understanding and solving related problems.

Magnification

The ratio of the height of the image to the height of the object.

Concave Mirror

A mirror with a surface that curves inward, causing light rays to converge.

Image Distance (di)

The distance from the mirror to the image formed.

Object Distance (do)

The distance from the mirror to the object being reflected.

Formula for Magnification using Height

M = hi / ho, where hi is height of image and ho is height of object.

Formula for Magnification using Distances

M = di / do, where di is image distance and do is object distance.

Virtual Image

An image that cannot be projected on a screen, having a negative magnification.

Real Image

An image that can be projected onto a screen, formed by converging light.

Units for Magnification

Magnification is expressed as a ratio or 'times' without units.

Power of 10

A method of expressing numbers in terms of a base, typically 10, to simplify calculations.
