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 ∣M∣=∣hiho∣=∣siso∣|M|=\left|\frac{h_{i}}{h_{o}}\right|=\left|\frac{s_{i}}{s_{o}}\right|∣M∣=​ho​hi​​​=​so​si​​​.

Define focal length (fff).

The distance from the mirror's surface to its focal point.

Define image magnification (MMM).

The ratio of the image size to the object size: ∣M∣=∣hiho∣=∣siso∣|M|=\left|\frac{h_{i}}{h_{o}}\right|=\left|\frac{s_{i}}{s_{o}}\right|∣M∣=​ho​hi​​​=​so​si​​​

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.
