The wavelength is #=410nm#

Explanation:

Frequency, wavelength and speed are related by the followig equation

#v=f* lambda#

#f=7.57*10^14 Hz#

#v=3*10^8ms^-1#

#lambda=v/f#

#=(310^8)/(7.5710^14)#

#=0.4*10^-6#

#=410*10^-9#

#=410nm#

This wavelength corresponds to the the violet of the visible spectrum
