What do waves transfer?
Energy
What happens when a sound wave hits a solid object?
Reflects
What is refraction?
The bending of light
What happens to light waves when they hit a concave mirror?
reflect and converge toward a focal point
What kind of wave is light?
Transverse
What is the law of reflection?
Why are leaves green?
They reflect green light and absorb the other colors
What happens to light waves when they hit a convex mirror?
Reflect and scatter
What kind of wave is sound?
Longitudinal
Why does sound travel faster through a denser medium?
Particles are closer together and energy transfers more quickly between them
What is the difference between displacement and distance?
Displace is a straight light from point A to point B; distance is the route you actually take
What happens to light waves when they hit a concave lens?
The higher the frequency...
the higher the pitch
What is frequency?
The number of waves that pass a certain point in a given amount of time.
Why do we see a rainbow when light passes through a prism?
the prism refracts the light, and each color has a different wavelength, bending at a different angle
What happens to light waves when they hit a convex lens?
Which kind of wave can travel through a vacuum?
Light waves
What is the Doppler Effect?
objects that radiate sound, and are moving, will cause the sound waves to compress, and an observer will hear a higher frequency before the object passes them
Why does refraction occur?
Waves travel at different speeds through different mediums.
What is the formula for acceleration?
final velocity - initial velocity / time
