The speed of sound in air is about 340 m/s. What is the wavelength of a sound wave with a frequency of 220 Hz?

##1.54bar(54) " meters"##

##"Hz" = "cycles"/"second"##

##"wavelength"## is measured as ##"meters"/"cycle"## ##color(white)("XXX")##or sometimes just ##"meters"## ##color(white)("XXX")## with the understanding that it means ##"meters per cycle"##

##(340 "meters"/cancel("second"))/(220 "cycles"/cancel("second"))##

##color(white)("XXX")=340/220 "meters"/"cycle"##

##color(white)("XXX")=1.54bar(54) "meters"/"cycle"##
