Optics Review

Front

What is a real image?

Back

A real image is an image formed by the convergence of light rays and is always inverted.

Front

What does the law of reflection state?

Back

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

Front

How does a virtual image appear?

Back

A virtual image appears upright and cannot be projected onto a screen.

Front

What type of mirror is used in flashlights and headlights?

Back

Concave mirrors are used in flashlights and headlights to focus light.

Front

What is the characteristic of virtual images?

Back

Virtual images are always erect and can be magnified or diminished.

Front

What is the difference between concave and convex mirrors?

Back

Concave mirrors converge light rays and can produce real images, while convex mirrors diverge light rays and produce virtual images.

Front

What is the focal point of a concave mirror?

Back

The focal point of a concave mirror is the point where parallel light rays converge after reflecting off the mirror.

Front

What happens to light rays that strike a convex mirror?

Back

Light rays that strike a convex mirror diverge, making the image appear smaller and farther away.

Front

What is magnification in optics?

Back

Magnification is the ratio of the height of the image to the height of the object, indicating how much larger or smaller the image appears.

Front

What is the significance of the center of curvature in mirrors?

Back

The center of curvature is the center of the sphere from which the mirror is a part, and it is twice the distance of the focal point.
