waves in physics
Question | Answer |
---|---|
v= f x lamda (upside down y) | wave speed |
bottom of a wave | trough |
the distance between identical points on 2 adjacent waves | wavelength |
the distance between the top (or bottom) to the resting position on a wave | amplitude |
the material that a mechanical wave passes through | medium |
wave that can travel through a vacuum (do not need a medium) | electromagnetic |
interference from "in sync" waves that add up | constructive |
wave hitting a surface and bouncing back into medium | reflection |
the time it takes to complete a wave cycle (T) | period |
the number of cycles completed in a certain period of time (f) | frequency |
T = 1/f | formula for period |
interference from "out of sync" waves that cancel each other out | destructive |
EM band with longest wavelength and lowest frequency | radio waves |
EM band with shortest wavelength and highest frequency | gamma rays |
f = 1/T | formula for frequency |
speed of light | 3.0 x 10^8 m/s |
speed of sound | 3.4 x 10^2 m/s |
