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

Front

What is an Electric Circuit?

Back

An electric circuit is a closed path through which electric current flows.

Front

What is Wave Period?

Back

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

Front

What is Wavelength?

Back

The distance from any point on a wave to the corresponding point on the next wave.

Front

What is Amplitude?

Back

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

Front

What is Wave Speed?

Back

Wave speed is the speed at which a wave travels; speed depends on the medium.

Front

What is the difference between an open and closed circuit?

Back

An open circuit does not allow current to flow, while a closed circuit does.

Front

How does changing the medium affect wave speed?

Back

Wave speed changes depending on the density and elasticity of the medium.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the significance of amplitude in sound waves?

Back

Amplitude determines the loudness of a sound; higher amplitude means louder sound.
