Paul Anderson explains wave properties, emphasizing their role in energy transfer. He covers key characteristics like wavelength, frequency, and amplitude, and discusses how waves interact with mediums and objects. The video also explores sound waves, interference, resonance, and practical applications in teaching. Advanced topics include refraction and resonance in musical instruments.

What is the primary function of a wave?

• To produce light

• To generate heat

• To move energy from place to place

• To create particles

What happens to sound in space?

• It cannot be heard

• It travels faster

• It changes frequency

• It becomes louder

What is resonance?

• The interference of waves that builds up or cancels out

• The bending of waves

• The transmission of waves

• The reflection of waves

How do waves interact with very small objects?

• They bend around the objects

• They slow down

• They reflect off the objects

• They miss the objects

What is refraction?

• The bending of waves as they pass from one medium to another

• The bouncing of waves off a surface

• The cancellation of waves

• The speeding up of waves

What is a good way to demonstrate simple waves in lower elementary grades?

• Using a prism

• Filling a pan with water and generating waves

• Using a string instrument

• Using a microphone

What are seismic waves?

• Waves in space

• Waves in the earth caused by disturbances

• Waves in the air

• Waves in the ocean
