What is a concave mirror?
A mirror that curves inward, also known as a converging mirror.
What is a convex mirror?
A mirror that bulges outward, also known as a diverging mirror.
What is a plane mirror?
A flat mirror that reflects light without converging or diverging.
Define focal length (f).
The distance from the mirror's surface to its focal point.
What is a real image?
An image formed when light rays converge in front of the mirror. It can be projected onto a screen.
What is a virtual image?
An image formed when light rays appear to diverge from behind the mirror. It cannot be projected onto a screen.
Define image magnification (M).
The ratio of the image size to the object size, given by .

Define focal length ().
The distance from the mirror's surface to its focal point.
Define image magnification ().
The ratio of the image size to the object size:
What is the effect of placing an object at the focal point of a concave mirror?
The reflected rays are parallel, and no image is formed.
What is the effect of a magnification value greater than 1?
The image is enlarged compared to the object.
What is the effect of a negative magnification value?
The image is inverted.
