Fast and Curious: Unit 8 Lesson 4, Lesson 5, and Lesson 6

Front

What is a Mechanical Wave?

Back

A wave that requires a medium through which to travel.

Front

What is Amplitude?

Back

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

Front

What is Direct Current (DC)?

Back

An electric current that flows in one direction.

Front

What is Resistance?

Back

The opposition presented to the current by a material or device.

Front

What is a Transverse Wave?

Back

A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling.

Front

What is the difference between Mechanical Waves and Electromagnetic Waves?

Back

Mechanical waves require a medium to travel, while electromagnetic waves do not.

Front

What is Frequency in relation to waves?

Back

The number of waves that pass a point in one second.

Front

What is Wavelength?

Back

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

Front

What is the relationship between Amplitude and Energy?

Back

Higher amplitude means more energy carried by the wave.

Front

What is the formula for calculating Wave Speed?

Back

Wave Speed = Frequency x Wavelength.
