Understanding Waves

What is a wave?

• A wave is a type of earthquake that happens in the ground.

• A wave is a type of sound that travels through air.

• A wave is a type of light that can travel through a vacuum.

• A wave is a disturbance that transfers energy from one place to another.

What are the two main categories of waves?

• Sound waves and water waves

• Seismic waves and light waves

• Transverse waves and longitudinal waves

• Mechanical waves and electromagnetic waves

In a transverse wave, how does the direction of the wave travel compared to the direction of the disturbance?

• The wave travels in a zigzag pattern.

• The wave travels perpendicular to the direction of the disturbance.

• The wave travels in the same direction as the disturbance.

• The wave travels in a circular motion.

In a longitudinal wave, how does the direction of the wave travel compared to the direction of the disturbance?

• The wave travels perpendicular to the direction of the disturbance.

• The wave travels in a zigzag pattern.

• The wave travels in the same direction as the disturbance.

• The wave travels in a circular motion.

What is an example of a mechanical wave?

• Sound wave

• Light wave

• Microwave

• Radio wave

Which type of wave does not require a medium to travel?

• Sound wave

• Seismic wave

• Water wave

• Electromagnetic wave

What is an example of a transverse wave?

• Sound wave

• Seismic wave

• Radio wave

• Water wave

What happens to air particles in a sound wave?

• They move in a circular motion.

• They move forward and backward.

• They move in a zigzag pattern.

• They move up and down.
