8 Science - Characteristics of Waves - Passage

What is a characteristic of transverse waves?

• The motion of the medium is parallel to the direction of the wave.

• The motion of the medium is perpendicular to the direction of the wave.

• They are only found in sound waves.

• They do not exist in the electromagnetic spectrum.

How does amplitude affect light in the electromagnetic spectrum?

• Higher amplitude results in dimmer light.

• Higher amplitude results in brighter light.

• Amplitude has no effect on light brightness.

• Amplitude only affects sound waves.
