Unit 4 Vocabulary (Light, Sound, EMS Waves)

Front

Wavelength

Back

The distance measured from any point on a wave to the corresponding point on the next wave.

Front

Amplitude

Back

The height of a wave, which varies based on the type of wave and indicates the amount of energy the wave carries.

Front

Energy

Back

The capacity to do work or produce change, which is carried by waves and affects their amplitude.

Front

Frequency

Back

The number of waves produced in a given period, typically measured in hertz (Hz).

Front

Inverse relationship

Back

A connection between two variables where an increase in one variable results in a decrease in the other.

Front

Wave Speed

Back

The speed at which a wave travels through a medium typically expressed in meters per second (m/s).

Front

Reflect

Back

To bounce back from a surface, as waves do when they encounter a barrier.

Front

Refract

Back

To change direction as a wave passes through different materials, resulting in a change in speed.

Front

Diffract

Back

To change direction and spread out when a wave encounters irregular surfaces or passes through openings.

Front

Longitudinal wave

Back

A type of wave in which the particles vibrate back and forth along the same direction in the medium, moving parallel to the direction the wave travels.
