10 things I need to know to pass the waves exam
1.)narrow opening + long wavelength = greatest diffraction effects
2.)electromagnetic waves to not require a medium to travel through
3.)frequency is directly proportional to energy
4.)T=1/f
5.)when a wave enters a new material the speed and wavelength can change; the frequency cannot
6.)all electromagnetic waves have a speed of 3 x 10^8 m/s
7.)n=c/v
8.)sound is a mechanical and longitudinal wave
9.)waves that have the same frequency and amplitude traveling in opposite directions create a standing wave
10.)period is the reciprocal of frequency - describes how long it takes for a single wave to pass a given point
