Which is true about waves?

• Waves carry energy and disturb the particles in the medium but do not carry the particles in the medium.

• Waves carry the particles in the medium across long distances.

• Any wave can travel through matter or empty space.

• The particles in a medium are carried with the wave.

What is the main difference between mechanical and electromagnetic waves?

• Both can travel through empty space.

• Electromagnetic waves can only travel through empty space; mechanical waves can only travel through a medium.

• Electromagnetic waves need a medium to travel through; mechanical waves can travel through empty space or a medium.

• Mechanical waves need a medium to travel through; electromagnetic waves can travel through empty space or a medium.

Sound waves travel fastest through:

• gases

• liquids

• solids

• empty space

What is changing in each of these waves?

• frequency

• wavelength

• amplitude

• speed
