Checkpoint 8 Review (units 8,9,10)

Front

What type of mirror is a plane mirror?

Back

A plane mirror is a flat mirror that reflects light to form a virtual image that is the same size as the object.

Front

What is the elemental spectrum used for?

Back

The elemental spectrum is used to identify the presence of specific elements in a star or other celestial bodies based on the light they emit.

Front

How does an image appear in a plane mirror?

Back

The image appears as a virtual image behind the mirror, laterally inverted, and the same distance from the mirror as the object.

Front

What is a common feature of longitudinal and transverse waves?

Back

Both types of waves transmit energy.

Front

Why are microwaves preferred over radio waves in telecommunications?

Back

Microwaves have a higher frequency, allowing them to transmit more data compared to radio waves.

Front

What is a concave mirror?

Back

A concave mirror is a mirror that curves inward, which can focus light to a point and can produce real or virtual images depending on the object's position.

Front

What is a convex mirror?

Back

A convex mirror is a mirror that curves outward, which always produces virtual images that are smaller than the object.

Front

What are crests and troughs in waves?

Back

Crests are the highest points of a wave, while troughs are the lowest points.

Front

What are rarefactions and compressions in longitudinal waves?

Back

Rarefactions are regions where particles are spread apart, and compressions are regions where particles are close together.

Front

What is the principle of reflection?

Back

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