#lambda~~8.6xx10^-9" m"#

Given: #f = 3.50 xx 10^16" s"^-1#

Use the equation:

#c = flambda#

where c is the the speed of light (#3.0xx10^8" m/s"#), #f# is the frequency (in Hz or #"s"^-1#), and #lambda# is the wavelength (in meters).

Solve the equation for #lambda#:

#lambda= c/f#

#lambda= (3.0xx10^8" m/s")/(3.50 xx 10^16" s"^-1)#

#lambda~~8.6xx10^-9" m"#
