What type of image is formed when an object is placed at the focal point of a concave mirror?
No image is formed; the reflected rays are parallel.
What effect does a magnification greater than 1 have on the image?
The image is enlarged.
What effect does a negative magnification have on the image?
The image is inverted.
Define concave mirror.
A mirror that curves inward, also known as a converging mirror.
Define convex mirror.
A mirror that bulges outward, also known as a diverging mirror.
Define plane mirror.
A flat mirror that reflects light without converging or diverging.
Define real image.
An image formed when light rays converge in front of the mirror; it can be projected onto a screen.
Define virtual image.
An image formed when light rays appear to diverge from behind the mirror; it cannot be projected onto a screen.
Define focal length ($f$).
The distance from the mirror's surface to its focal point.
Define image magnification ($M$).
The ratio of the image size to the object size: $|M|=\left|\frac{h_{i}}{h_{o}}\right|=\left|\frac{s_{i}}{s_{o}}\right|$
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.
