Chapter 14 Lesson 1: Waves

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, which allows sound waves to change direction when passing through an open doorway.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in a certain amount of time, usually measured in hertz (Hz).

Front

What is wavelength?

Back

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

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's travel, such as sound waves.

Front

What are waves?

Back

Waves are rhythmic disturbances that carry energy through a medium, such as water, air, or solid materials.

Front

What is amplitude?

Back

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

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the direction of the wave, while in longitudinal waves, particles move parallel to the direction of the wave.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves like light.

Front

What is an example of a longitudinal wave?

Back

An example of a longitudinal wave is a sound wave traveling through air.

Front

What is the relationship between frequency and wavelength?

Back

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