Mirrors

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 inverted and can be captured on a surface.

Front

What is a virtual image?

Back

A virtual image is formed when light rays appear to diverge from a point. It cannot be projected onto a screen and is upright.

Front

What is the focal length of a mirror?

Back

The focal length is the distance from the mirror's surface to the focal point, where parallel rays of light converge.

Front

If the focal length is 10 cm and the object is placed 15 cm away, where is the image located?

Back

30 cm away from the mirror.

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

If Θ1 is 70 degrees, what is Θ2?

Back

Θ2 is 20 degrees.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

All electromagnetic waves travel at the same speed in a vacuum, which is approximately 3 x 10^8 m/s.

Front

What is a concave mirror?

Back

A concave mirror is a mirror that curves inward, causing parallel incoming light rays to converge at a focal point.

Front

What is a convex mirror?

Back

A convex mirror is a mirror that bulges outward, causing parallel incoming light rays to diverge.

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 segment. It is twice the focal length.
