SPS9 Waves Review flashcard

Front

What is the difference between electromagnetic waves and mechanical waves?

Back

Mechanical waves require a medium to travel, while electromagnetic waves can travel through a vacuum.

Front

What is true about the energy of visible light waves?

Back

Visible light waves with shorter wavelengths have more energy.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) = Speed (v) / Wavelength (λ).

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 345 m/s.

Front

What type of wave is sound?

Back

Sound is a mechanical wave.

Front

What type of wave is light?

Back

Light is an electromagnetic wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.
