Build-A-Wave
This wave property is the distance from one crest to the next crest.
What is wavelength
In a transverse wave, particles move in a direction that is __________ to the direction of energy transfer.
What is perpendicular
When a wave bounces off a surface, this interaction is called __________.
What is reflection
These waves can travel through empty space and do not need a medium.
What are electromagnetic waves
Cell phones use which type of wave to send and receive information?
What is radio waves
This property of a wave tells how much energy the wave carries.
What is amplitude
In a longitudinal wave, particles move __________ to the direction of wave travel.
When a wave slows down and bends as it enters a new medium, this interaction is called __________.
What is refraction
Which electromagnetic wave has the longest wavelength?
What is radio waves
Sound travels through the air by causing __________ in air particles
What is vibrations
If the frequency of a wave increases, what happens to its wavelength, assuming the wave speed stays the same?
What is wavelength decreases
What happens to the energy of a wave when its amplitude increases?
What is energy increases
Dark‑colored materials get hotter in sunlight because they absorb more wave __________.
What is energy
As you move from radio waves to gamma rays, what happens to energy?
What is energy increases
Why can sound not travel through space?
What is sound needs a medium, and space has none?
Two waves travel through the same medium at the same speed.
One wave has a higher frequency.
Which wave has more energy, and why?
What is the wave with higher frequency because higher frequency means more energy?
Why does a wave transfer energy without permanently transferring matter?
What is particles vibrate around a fixed position while energy moves forward?
Why do we see a straw look bent in a glass of water?
What is light refracts as it moves from air to water
Why are X‑rays useful in medical imaging but dangerous in high amounts?
What is they have high energy that can pass through tissue but damage cells?
Explain how changing a sound wave’s frequency affects the sound we hear.
What is higher frequency means higher pitch
A student increases the vibrations of a sound source.
Explain two wave properties that change and how they change.
What are frequency increases and wavelength decreases?
Explain why shaking a rope harder makes larger waves but does not make the wave travel faster.
What is amplitude increases energy, but wave speed depends on the medium, not strength
Design a pair of sunglasses that reduces glare from water.
Which wave interaction should be increased, and why?
What is absorption or reflection to reduce reflected light reaching the eyes
Which electromagnetic wave would be most effective for long‑distance communication, and why?
What are radio waves because they travel far and carry information efficiently?
Compare how light waves and sound waves are used to transfer information in everyday technology.
What is light uses EM waves (Wi‑Fi, fiber optics); sound uses vibrations in media for speech and audio
