Q2 Exam Vocab

Front

Light Waves

Back

Describe how light waves are reflected, absorbed, or transmitted through materials.

Front

Expression of Waves

Back

Frequency and wavelength affect how a wave is expressed.

Front

Reflected Waves

Back

Describe how waves are reflected through various materials.

Front

Transmitted Waves

Back

Describe how waves are transmitted through various materials.

Front

Wavelength

Back

The distance between two identical points on consecutive waves, such as two crests or two troughs.

Front

The number of waves that pass a certain point in one second, measured in Hertz (Hz) where 1 Hz equals 1 wave per second.

Back

Frequency

Front

Volume

Back

Related to amplitude; louder sounds have greater amplitude.

Front

Reflection

Back

When a wave hits a barrier or boundary between two materials, it bounces off and changes direction, reflecting back towards the source.

Front

When a wave bends or changes direction as it moves from one medium (like air) to another medium (like water), because the wave speed changes in the different materials.

Back

Refraction

Front

Absorption

Back

When a wave transfers its energy to a medium, such as a solid, liquid, or gas, that it passes through.
