Click reset. select transverse waves. select lights on and show grid and turn off show rulers. set the frequency to 0.50 hz. a single cycle is the time it takes the hand to move up, move down, and then back up to the starting position. click play, and then click pause after exactly one cycle. (this may take a few tries.) how long does one cycle take? this is the period (t) of the wave. frequency (f) is equal to 1 divided by the period: f = . frequency is measured in hertz (hz), where 1 hz = 1 cycle/sec. what is the frequency of this wave? answers

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s. part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
