What is the wavelength of light in water if it has a frequency of 6.8 x 10^14 Hz? I don't know what formula to use and don't understand. I tried Lambda=c/v and got it wrong. Answer needs to be in nm. Thanks.

What are you using for c? The velocity of light in water is lower than in a vacuum, which you know I am sure from your experience trying to shoot fish with a bow and arrow. If you are using about 3*10^8 m/s, that is wrong.

Thanks for letting me know that 3*10^8 is wrong. That's why my answer is wrong. So, will continue searching for what to use for c. Don't understand. Thanks again.

The link tells you right off.
2.25*10^8
instead of 3*10^8
