Waves: Longitudinal Waves

The video tutorial uses a slinky to demonstrate longitudinal waves, highlighting how these waves move horizontally rather than vertically. It explains the concepts of compression and rarefaction, where particles collide and separate as the wave progresses. The tutorial also discusses sound waves as a type of longitudinal wave, providing examples such as those produced by airplanes, explosions, and special hammers.

What is the primary direction of movement for a longitudinal wave?

• Up and down

• Horizontally

• Diagonally

• In a circular motion

What occurs when particles in a longitudinal wave collide?

• They form a rarefaction

• They create a vacuum

• They stop moving

• They compress

What is the term used when particles in a longitudinal wave move apart?

• Compression

• Expansion

• Rarefaction

• Diffusion

Which of the following is an example of a powerful sound wave?

• A whisper

• A firecracker explosion

• A gentle breeze

• A flowing river

What powers the special hammers mentioned in the video?

• Electricity

• Hydraulics

• Solar energy

• Cartridges and gunpowder
