Understanding Waves and Wavelengths

David, Rohan, and Benjamin are having a debate about waves. What is a wave?

• A disturbance that moves energy from one place to another

• A disturbance that moves matter from one place to another

• A disturbance that creates light and sound

• A disturbance that creates earthquakes and tsunamis

Emma, Kai, and Grace are having a debate about waves. They want to know what the medium through which a wave moves is. Can you help them?

• Matter

• Energy

• Space

• Medium

Grace, Luna, and Scarlett are observing a wave passing through a medium. What happens to the medium when the wave passes through it?

• It moves back and forth repeatedly

• It stays in one place

• It disappears

• It transforms into energy

Nora, Ethan, and Mason are having a friendly debate about waves. They want to know what the high points in a wave are called. Can you help them?

• Crests

• Troughs

• Mediums

• Wavelengths

Imagine Daniel, Noah, and Kai are surfing. They are trying to identify the low points in the waves they are riding. What are these low points called?

• Troughs

• Crests

• Mediums

• Wavelengths

Ethan, Maya, and William are having a debate. Ethan thinks that light is an electromagnetic wave, while Maya thinks it's a sound wave. William, on the other hand, believes it's a seismic wave. Who do you think is correct?

• Ethan (Electromagnetic wave)

• Maya (Sound wave)

• William (Seismic wave)

• None of them

Emma, Ava, and Priya are on a beach, watching the waves roll in. They start a fun debate: What is the distance from one point on a wave to an identical point on the next called?

• Wavelength

• Frequency

• Crest

• Trough

Anika, Harper, and Isla are having a friendly competition to see who can make the best paper boat. They notice that the waves in the water are affecting their boats differently. What property of a wave describes how many waves pass one point during one second, which might be affecting their boats?

• Frequency

• Wavelength

• Crest

• Trough

Aiden, Kai, and Maya are having a debate about waves. They want to know how frequency and wavelength are related to the amount of energy a wave has. Can you help them settle the debate?

• Higher frequency waves have more energy

• Higher wavelength waves have more energy

• Frequency and wavelength are not related to energy

• All waves have the same amount of energy
