Waves and Electromagnetic Waves

What are waves?

• Disturbances that carry energy from one place to another

• Particles that move in a circular motion

• Sound produced by vibrations

• Light emitted by the sun

Which of the following is NOT an example of a mechanical wave?

• Slinky waves

• Sound waves

• Water waves

• Electromagnetic waves

What is the medium through which slinky waves travel?

• Air

• Water

• Vacuum

• Slinky

What type of wave is created when each coil of a slinky moves perpendicular to the direction of the wave?

• Transverse wave

• Longitudinal wave

• Electromagnetic wave

• Mechanical wave

What is the wavelength of a wave?

• The distance from one crest to the next

• The distance from one trough to the next

• The distance from one crest to the trough

• The distance from one wave to another

What is the amplitude of a wave?

• The height of the crest

• The depth of the trough

• The distance from one crest to the trough

• The distance from one wave to another

What happens when two waves meet?

• They pass straight through each other

• They bounce off each other

• They combine to form a larger wave

• They cancel each other out

What is the frequency of a wave?

• The number of complete wavelengths that pass a given point per second

• The speed at which the wave travels

• The distance from one crest to the next

• The height of the crest
