9.1 Mechanical Waves reading review

What do mechanical waves require to propagate?

• A medium such as air, water, or solid materials

• A vacuum

• Electromagnetic fields

• No medium is required

Unlike ______ waves, mechanical waves cannot travel through a vacuum

What are the 3 types of mechanical waves

Which type of mechanical wave involves particles vibrating perpendicular to the wave's direction of travel?

• Transverse waves

• Longitudinal waves

• Surface waves

• Electromagnetic waves

What is an example of a longitudinal wave?

What type of motion do particles exhibit in surface waves?

• Circular motion

• Up-and-down motion only

• Back-and-forth motion only

• No motion

Which property of a medium affects the speed of sound waves?

• Density

• Color

• Shape

• Magnetism

sound waves travel--------- in denser materials because the particles are closer together, allowing energy to transfer more efficiently.

how does temperature effect the speed of the wave?

What is an example of a practical application of seismic waves?

• Predicting earthquakes

• Designing musical instruments

• Improving wireless communication

• Studying ocean currents
