Mirrors and Lenses

Front

What is a convex mirror?

Back

A convex mirror is a curved mirror that bulges outward, causing light rays to spread out. It produces virtual images that are smaller than the object.

Front

What type of image can a convex lens produce?

Back

A convex lens can produce both real and virtual images depending on the position of the object relative to the lens.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror.

Front

What is a virtual image?

Back

A virtual image is an image formed by rays of light that appear to diverge from a point, but do not actually converge. It cannot be projected on a screen.

Front

What is a real image?

Back

A real image is formed when light rays converge and can be projected onto a screen. It is usually inverted.

Front

What happens to light rays when they hit a concave mirror?

Back

Light rays that hit a concave mirror converge to a focal point, allowing it to produce real images.

Front

What is the focal point of a lens?

Back

The focal point of a lens is the point where parallel light rays either converge (in a convex lens) or appear to diverge from (in a concave lens).

Front

What is the difference between a concave lens and a convex lens?

Back

A concave lens diverges light rays and produces virtual images, while a convex lens converges light rays and can produce both real and virtual images.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.
