6th Grade Waves Review

Front

What property of this wave is represented by the letter "A"?

Back

wavelength

Answer explanation

The letter 'A' represents the wavelength of the wave, which is the distance between successive crests or troughs. Amplitude refers to the height, while crest and trough describe specific points on the wave.

Front

What property of the wave is represented by the letter "B"?

Back

amplitude

Answer explanation

The letter 'B' represents the amplitude of the wave, which is the maximum height of the wave from its rest position. It indicates the energy of the wave; higher amplitude means more energy.

Front

The highest point on a wave is:

Back

the crest

Answer explanation

The highest point on a wave is called the crest. The trough is the lowest point, while the top and the coast are not specific terms used in wave terminology.

Front

The number of wavelengths that pass a point each per second is:

Back

frequency

Answer explanation

The number of wavelengths that pass a point each second is called frequency. It measures how often a wave cycles in a given time, making frequency the correct choice over period, longitudinal, or transverse wave.

Front

The lowest point on a wave is the:

Back

Trough

Answer explanation

The lowest point on a wave is called the trough. It is the opposite of the crest, which is the highest point. Amplitude refers to the height of the wave, while wavelength is the distance between successive crests or troughs.

Front

The type of waves that require medium to pass:

Back

Mechanical Waves

Answer explanation

Mechanical waves require a medium, such as air, water, or solid materials, to propagate. In contrast, electromagnetic waves can travel through a vacuum, making mechanical waves the correct choice.

Front

Vocabulary term for the distance between points C & G?

Back

Wavelength

Answer explanation

The term 'wavelength' refers to the distance between two points in a wave, such as points C and G. It is a key concept in wave physics, distinguishing it from amplitude, crest, and frequency.

Front

When the frequency of a wave increases, what happens to the wavelength?

Back

The wavelength decreases.

Answer explanation

When the frequency of a wave increases, the wavelength decreases. This is because the speed of the wave remains constant, and according to the wave equation (speed = frequency x wavelength), an increase in frequency results in a shorter wavelength.

Front

A mechanical wave cannot travel through...

Back

a vacuum (empty space).

Answer explanation

A mechanical wave requires a medium to travel through, such as water, air, or glass. It cannot travel through a vacuum (empty space) because there are no particles to transmit the wave.

Front

Which letter(s) represent the trough of the wave?

Back

D

Answer explanation

The trough of a wave is the lowest point. In the given options, only D represents a trough, making it the correct answer. A, B, C, and G do not represent troughs.
