#0.386 m# (#3# s.f.)

Explanation:

wave equation: #s = flambda#

speed = frequency * wavelength

speed is in #m//s#, frequency is in #Hz# and wavelength in #m#.

this means that the unit for #(340 m//s)/(880 Hz)# is metres #m#.

#340/880 = 17/44#

#17/44 = 0.386386386...#

#=~ 0.386# (#3# s.f.)

rounded to #3# significant figures, #(340 m//s)/(880 Hz) = 0.386 m#.

Approximately #0.386# meters.

Explanation:

We are given:

#(340 \ "m/s")/(880 \ "Hz")#

Note that #1 \ "Hz"=1 \ "s"^-1#.

And so, we got:

#=(340 \ "m s"^-1)/(880 \ "s"^-1)#

#~~0.386 \ "m"#

This is probably a case of frequency, velocity, and wavelength problem.

The equation for it is:

#v=flambda#

  • #v# is the velocity in meters per second

  • #f# is the frequency in hertz

  • #lambda# is the wavelength in meters
