Answer:

#1.54bar(54) " meters"#

Explanation:

#"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"#
