Understanding Waves

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

• To create sound

• To transfer energy

• To generate heat

• To produce light

How is frequency measured according to the second section?

• By the color of the wave

• By the amplitude of the wave

• By counting the number of vibrations

• By the speed of light

What causes waves to be in motion?

• A change in temperature

• A gravitational pull

• A vibration

• A magnetic field

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

• Electromagnetic wave

• Longitudinal wave

• Transverse wave

• Surface wave

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

• Perpendicular

• Parallel

• Circular

• Diagonal
