Understanding Waves

What are the two main categories of waves?

• Mechanical and electromagnetic waves

• Transverse and longitudinal waves

• Sound and water waves

• Light and radio waves

Which type of wave requires a medium to travel through?

• Mechanical waves

• Electromagnetic waves

• Transverse waves

• Longitudinal waves

In transverse waves, how does the disturbance move in relation to the direction of the wave?

• Perpendicular

• Parallel

• In the same direction

• Opposite direction

What property of a wave indicates the amount of energy it carries?

• Amplitude

• Wavelength

• Frequency

• Period

What happens during the refraction of a wave?

• The wave changes direction as it moves from one medium to another

• The wave bounces back after hitting an obstacle

• The wave bends around a small obstacle or opening

• Two waves interact, either constructively or destructively
