6th Grade Mechanical Waves

Front

What type of wave always requires a medium?

Back

Mechanical waves require a medium to travel through, such as air, water, or solid materials.

Front

What is the term for the number of times a pattern repeats itself in a wave?

Back

Frequency is the number of cycles of a wave that occur in a given time period, usually measured in Hertz (Hz).

Front

What is the term for the amount of sound energy that travels through a medium in one second?

Back

Intensity refers to the power of sound energy per unit area, often measured in watts per square meter.

Front

What type of waves have particles that move PERPENDICULARLY to the direction the wave is traveling?

Back

Transverse waves are characterized by particle motion that is perpendicular to the direction of wave propagation.

Front

What does dB stand for in the context of sound volume?

Back

dB stands for Decibels, a unit used to measure the intensity of sound.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is a medium in terms of wave propagation?

Back

A medium is a substance through which a wave can travel, such as air, water, or solid materials.
