Unit 4 Waves Lesson 1 and 2

What is the definition of a wave?

• A wave is a disturbance that transfers matter through a medium or space without transferring energy.

• A wave is a disturbance that transfers energy through a medium or space while transferring matter.

• A wave is a disturbance that transfers energy through a medium or space without transferring matter.

• A wave is a disturbance that does not transfer energy through a medium or space.

Explain the difference between transverse and longitudinal waves.

• Transverse waves move perpendicular to the direction of the wave, while longitudinal waves move parallel to the direction of the wave.

• Transverse waves have higher frequency than longitudinal waves.

• Transverse waves move in a straight line, while longitudinal waves move in a zigzag pattern.

• Transverse waves can only travel through solids, while longitudinal waves can only travel through liquids.

Give an example of a transverse wave.

• Light wave

• Longitudinal wave

• Electromagnetic wave

• Sound wave

Give an example of a longitudinal wave.

• Tsunamis

• Sound waves

• Electromagnetic waves

• Water waves

What is the amplitude of a wave?

• The energy of the wave.

• The maximum disturbance in the medium from its equilibrium position.

• The speed of the wave

• The frequency of the wave

What is frequency

• Frequency and pitch are inversely proportional.

• Frequency has no effect on pitch.

• the number of wavelengths that pass a point per second

• Frequency and pitch are unrelated.

What is the wavelength of a wave?

• The wavelength of a wave is the speed of the wave.

• The wavelength of a wave is the amplitude of the wave.

• The wavelength of a wave is the distance from a point on one wave to the same point on the next wave.

• The wavelength of a wave is the frequency of the wave.

Describe how waves transfer energy.

• Waves transfer energy by increasing the density of the medium.

• Waves transfer energy by changing the color of the medium.

• Waves transfer energy by creating heat in the medium.

• Waves transfer energy by causing particles in the medium to oscillate back and forth.

Explain the concept of wave interference.

• Wave interference is the result of waves reflecting off a surface.

• Wave interference is the phenomenon where waves cancel each other out completely.

• Wave interference is the phenomenon where two or more waves superpose to form a resultant wave of greater, lower, or the same amplitude.

• Wave interference only occurs with sound waves, not light waves.

How does the speed of a wave change when it moves from one medium to another?

• The speed of a wave changes when it moves from one medium to another due to the change in the medium's properties.

• The speed of a wave remains constant in all mediums

• The speed of a wave increases when it moves to a different medium

• The speed of a wave decreases when it moves to a different medium
