Hello guys.
I have a problem that i cannot solve for some reason.
I have a transparent optical enviroment with refractive index = 1,2. Light falls on this enviroment with frequency f = 5 . 1e+14 Hz. Also the speed of light is c = 3 . 1e+8 m/s
How do I calculate the wavelenght from this?
Thank you for your help :-)
