Properties and Functions of Mirrors

The video tutorial explains how light waves travel and reflect off mirrors, forming images. It covers plane mirrors, which create upright virtual images, and concave mirrors, which form real, inverted images. Convex mirrors produce virtual images that are smaller and upright. The tutorial also discusses the practical uses of these mirrors, such as in vehicles and stores, and highlights the differences in image perception due to mirror shapes.

What happens to light waves when they hit a smooth surface like a mirror?

• They are scattered in all directions.

• They pass through the surface.

• They are absorbed by the surface.

• They are reflected to form images.

How does your reflection appear in a plane mirror?

• Upright and the same size

• Upside down and smaller

• Distorted and unclear

• Larger and inverted

What is a virtual image?

• An image that appears to be behind the mirror

• An image that is smaller than the object

• An image that can be projected on a screen

• An image that is upside down

What is the focal point in a concave mirror?

• The point where light rays converge

• The point where light rays are scattered

• The point where light rays are absorbed

• The point where light rays diverge

How does a real image formed by a concave mirror appear?

• Upright and larger

• Upside down and smaller

• Upright and smaller

• Upside down and larger

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

• They spread apart after reflection.

• They pass through the mirror.

• They converge at a focal point.

• They are absorbed by the mirror.

Why are convex mirrors used in places like grocery stores?

• They focus light to a single point.

• They create real images.

• They allow large areas to be viewed.

• They make objects appear larger.

What warning is often found on automobile side view mirrors?

• Objects in mirror are larger than they appear.

• Objects in mirror are closer than they appear.

• Objects in mirror are farther than they appear.

• Objects in mirror are smaller than they appear.

Which type of mirror always forms a virtual image?

• All of the above

• Plane mirror

• Concave mirror

• Convex mirror

What is the main difference in the way concave and convex mirrors reflect light?

• Concave mirrors focus light, convex mirrors spread it.

• Concave mirrors absorb light, convex mirrors reflect it.

• Concave mirrors spread light, convex mirrors focus it.

• Both reflect light in the same way.
