Wave Types
What type of wave moves particles up and down while energy moves forward?
Light Waves
What is the highest point of a transverse wave?
Crest
What do we call it when a wave bounces off a surface?
Reflection
What type of wave behavior do sunglasses use to protect your eyes?
Absorption and some Reflection
What word means "the resting position" of a wave?
Equilibrium
hat type of wave moves particles back and forth in the same direction as the energy travels?
Sound Waves
What is the lowest point of a transverse wave?
Trough
What do we call it when a wave passes through a material?
Transmission
Why are blackout curtains good for blocking light?
They absorb and reflect light
What word describes the number of waves that pass a point in one second?
Frequency
Sound waves are an example of which type of wave?
Longitudinal Waves
What do we call the distance between two crests or two troughs?
Wavelength
What do we call it when a wave’s energy is taken in by a material?
Absorption
Why would clear plastic not make a good blackout curtain?
It transmits light
If a wave has a high frequency, what happens to its wavelength?
It gets shorter/decreases
Which type of wave can travel through space without a medium?
Light Waves
What is the distance from the equilibrium line to a crest called?
Amplitude
Which interaction makes a black t-shirt feel hotter in the sun?
Absorption
Why is sound quieter after passing through a thick wall?
Absorption of sound waves
If a wave has a large amplitude, what does that mean about its energy?
It is stronger/it has more energy.
Give one real-world example of each: transverse wave and longitudinal wave.
Transverse – light/water wave; Longitudinal – sound wave
What is the total distance from a wave’s crest to its trough?
Wave Height
Which interaction explains how we see ourselves in a mirror?
Reflection
How do noise-canceling headphones use wave interactions to block sound?
They absorb and cancel sound waves
Which three ways can waves interact with materials?
Reflection, absorption, transmission
