Unit 5 TEST - Waves 8.8AB - 8th Science

Front

What is a longitudinal wave?

Back

A wave in which the medium moves parallel to the direction of the wave's travel, such as sound waves.

Front

What is a transverse wave?

Back

A wave in which the medium moves perpendicular to the direction of the wave's travel, such as light waves.

Front

What is the relationship between wavelength and frequency?

Back

The longer the wavelength, the lower the frequency; the shorter the wavelength, the higher the frequency.

Front

What type of wave has a wavelength of 10^3 meters?

Back

Radio waves.

Front

How do you determine which wave has the greatest frequency in a diagram?

Back

The wave with the shortest wavelength has the greatest frequency.

Front

What is amplitude in a wave?

Back

The maximum distance that the medium moves from its rest position; it is related to the energy of the wave.

Front

What is the definition of frequency?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is a surface wave?

Back

A wave that travels along the surface of a medium, exhibiting characteristics of both transverse and longitudinal waves.

Front

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

Back

Approximately 343 meters per second.

Front

What is an electromagnetic wave?

Back

A wave that can travel through a vacuum and does not require a medium, such as light waves.
