Wave Basics
What do waves transfer—matter or energy
What is energy?
Through what can sound not travel?
What is a vacuum?
What particle carries electromagnetic energy?
What is a photon?
What law says light reflects at the same angle it strikes?
What is the law of reflection?
What is the spread-out part of a compressional wave?
What is a rarefaction?
What kind of wave has vibrations that are perpendicular to its direction of motion?
What is a transverse wave?
What happens when sound reflects off a solid surface?
What is an echo?
Which electromagnetic wave has the most energy?
What is an X-ray wave?
What kind of mirror magnifies objects by converging light?
What is a concave mirror?
What type of object lets only some light through?
What is translucent?
What type of wave requires a medium to travel through?
What is a mechanical wave?
What do we call the change in pitch caused by a moving sound source?
What is the Doppler effect?
What is the full range of electromagnetic waves called?
What is the electromagnetic spectrum?
What kind of lens makes things appear smaller?
What is a concave lens?
Why can’t compressional waves move through a vacuum?
Because there's no medium to carry the vibrations.
How do you calculate wave speed?
What is wavelength times frequency?
Which travels faster—sound in warm air or cold air?
What is warm air?
Name one use of electromagnetic energy.
What is communication/medical technology/light/heat?
What is bending of light called when it passes through different materials?
What is refraction?
Why is a gymnasium often loud and echoey?
Sound reflects off hard surfaces.
Which wave property tells how many waves pass a point in a given time?
What is frequency?
What 3 properties define a sound wave?
What are pitch, loudness, and intensity?
What type of electromagnetic wave is used to disinfect water?
What is ultraviolet light?
What are the primary colors of light?
What are red, green, and blue?
We see the Sun before it rises. Why?
Light refracts through Earth’s atmosphere.
