Review of Waves, Chapter 7 and 8

Front

What is the speed of light?

Back

The speed of light is 300 million meters per second.

Front

Which form of message transmission is less likely to experience distortion or noise?

Back

Digital transmission is less likely to experience distortion or noise.

Front

How could you generate a sound with a higher pitch?

Back

You can generate a sound with a higher pitch by increasing the frequency.

Front

What is the electromagnetic wave with the shortest wavelength?

Back

Gamma rays have the shortest wavelength among electromagnetic waves.

Front

In visible light, which color has the longest wavelength?

Back

Red light has the longest wavelength in the visible spectrum.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What is frequency?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What are sound waves?

Back

Sound waves are longitudinal waves that travel through a medium, such as air, water, or solids.
