If a light wave has a wavelength of 5.80x10^-7 what is its frequency

Speed = v = 3×10⁸ m/s

Wavelength = λ = 5.8×10⁻⁷ m

Frequency = f  

v = fλ

Hence,

f = v/λ

f = 3×10⁸ / 5.8×10⁻⁷

f = 0.517×10⁸⁺⁷

f = 5.17×10¹⁴ Hz                                                                                                                                  

i hope this will help but if im wrong then it will be 5.16x10¹⁴
