all possible wavelengths that can be made form a standing wave.
it is the same as the fundamental frequency. Having a standing wave with the least amount of nodes possible. Two... - 1st harmonic- L= 1/2 wavelength
occurs when wavelength= Length
wavelength= 2L/n n= all numbers
wavelength = 4L/n n= odd numbers
measures how off two sounds are in pitch. The difference in frequency = the pitch you will hear
intensity increases with the square of the frequency and the square of the amplitude.
Mass and energy.
temperature. - Velocity is determined by medium and molecules move faster in a hot gas than in a cold gas.
1. Mechanical - must have a medium to travel and an initial energy input. ex: sound and ocean waves 2. electromagnetic- its the wave created and absorbed by charged particles (ex photons) and has a magnetic and electric components. ex: radio and x-rays. 3. Matter waves-... may not need to know.
