#2.95*10^-12 \ "m"#

Explanation:

The wavelength equation is:

#lambda=v/f#

  • #v# is the velocity in meters per second

  • #f# is the frequency in hertz

So, we got:

#lambda=(340"m"color(red)cancelcolor(black)"s"^-1)/(1.151*10^14color(red)cancelcolor(black)"s"^-1# #(because 1 \ "Hz"=1 \ "s"^-1)#

#=2.95*10^-12 \ "m"#
