Chapter 15 - Waves

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

Front

What does wavelength represent in a wave?

Back

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

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through, while electromagnetic waves can travel through a vacuum.

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.

Front

How does increasing amplitude affect a wave's energy?

Back

Increasing amplitude means the wave is carrying more energy.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum; it requires a medium.

Front

What is an example of an electromagnetic wave?

Back

Light waves, radio waves, and X-rays are examples of electromagnetic waves.
