A laser used in eye surgery to fuse detached retinas produces radiation with a wavelength of 6.4 x 10^-7 m. What is the frequency of the laser? Speed of light = 3.00 x 10^8 m/s

(Hint: Remember to round your answer to the lowest number of significant figures.)

(Speed of light) / (Wavelength) = Frequency

show steps please.
