What determines if a wave is classified as transverse or longitudinal?

• The material the wave travels through

• The direction of particle vibration relative to the wave's energy movement

• The frequency of the wave

• The amplitude of the wave

What are compressions and rarefactions associated with?

• Transverse waves

• Longitudinal waves

• Electromagnetic waves

• None of the above

How do sound waves travel through air?

• By electromagnetic radiation

• By transferring energy through particle vibration parallel to the wave direction

• By causing air particles to vibrate up and down

• By moving air particles in a circular motion

What is the direction of particle vibration in transverse waves?

• Parallel to the direction of energy movement

• At a 45-degree angle to the direction of energy movement

• Perpendicular to the direction of energy movement

• In the same direction as the wave travels

Which of the following is an example of a transverse wave?

• Sound waves

• Seismic P-waves

• Water surface waves

• None of the above

What is essential for the existence of the modern world and our daily lives, yet is invisible?

• Gravity

• Electromagnetic radiation

• Air

• Sound

How do electromagnetic waves differ from ocean waves?

• They require water to travel

• They can only travel through air

• They can travel through the vacuum of space

• They have no frequency

What determines the frequency of an electromagnetic wave?

• The height of the wave

• The number of crests passing a point per second

• The speed of light

• The distance between crests

Which waves have the shortest wavelength and highest energy in the electromagnetic spectrum?

• Gamma rays

• Infrared waves

• Microwaves

• Radio waves
