Understanding Waves

What is the primary function of waves as discussed in the first section?

• To produce heat

• To generate light

• To transfer energy

• To create sound

How is frequency measured according to the second section?

• By the speed of light

• By counting the number of vibrations

• By the amplitude of the wave

• By the color of the wave

What causes waves to be in motion?

• A shift in pressure

• A vibration

• A change in temperature

• A magnetic field

Which type of wave involves particles moving parallel to the direction of the wave?

• Longitudinal wave

• Surface wave

• Electromagnetic wave

• Transverse wave

In a transverse wave, how do particles move relative to the wave direction?

• Perpendicular

• Circular

• Diagonal

• Parallel
