Fast and Curious: Unit 8 Lesson 4 - Waves as Energy

Front

What is an Electromagnetic Wave?

Back

A wave consisting of changing electric and magnetic fields, that is emitted by vibrating electric charges and can travel through a vacuum.

Front

What is Frequency?

Back

The number of cycles, such as waves, in a given amount of time.

Front

What is a Mechanical Wave?

Back

A wave that requires a medium through which to travel.

Front

What is Wave Period?

Back

The time required for corresponding points on consecutive waves to pass a given point.

Front

What is Amplitude?

Back

The maximum distance that the particles of a wave’s medium vibrate from their rest positions.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength is inversely proportional to frequency; as frequency increases, wavelength decreases.

Front

What is a Transverse Wave?

Back

A wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a Longitudinal Wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is the speed of a wave?

Back

The distance a wave travels in a given amount of time, calculated as speed = wavelength x frequency.

Front

What is a Wave?

Back

A disturbance that transfers energy from one place to another without transferring matter.
