Waves: Sound and Light Unit

Front

What does medium refer to?

Back

The type of matter (solid, liquid, gas) through which waves travel.

Front

What determines the pitch of sound?

Back

The pitch of sound is mainly determined by frequency.

Front

What determines the loudness of sound?

Back

The loudness of sound is mainly determined by amplitude.

Front

In which medium does light travel the slowest?

Back

Light travels slowest in solids.

Front

How does the sound change as a car approaches and then moves away from an observer?

Back

The sound changes from high pitch to low pitch from the perspective of the observer.

Front

What determines the color of an object?

Back

The wavelengths of the light waves that are reflected determine the object's color.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through matter or space.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves and electromagnetic waves.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the wave direction; in longitudinal waves, it is parallel.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).
