Mechanical waves, part 2

Front

In which medium do sound waves travel fastest?

Back

Sound waves travel fastest in solids, such as a table.

Front

Sound waves are made of chains of vibrating _______.

Back

Sound waves are made of chains of vibrating molecules.

Front

All waves transmit _________ NOT _________.

Back

All waves transmit energy, NOT matter.

Front

The number of wavelengths that pass a given point in 1 second is the wave's ___.

Back

The number of wavelengths that pass a given point in 1 second is the wave's frequency.

Front

What is the relationship between amplitude and energy in waves?

Back

Higher amplitude means more energy in a wave.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium to travel through.

Front

What are the two main types of mechanical waves?

Back

The two main types of mechanical waves are transverse waves and longitudinal waves.

Front

Define transverse wave.

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave.

Front

Define longitudinal wave.

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave.

Front

What is wavelength?

Back

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