Calculate the wavelength of the yellow light emitted by a Sodium Lamp if the frequency is 5.10 X 10^14 Hz.

Formula:
Wavelenght (lamda)= speed of light, 3 X 10^8(c)/frequency, 5.1 X 10^14.

My answer was 5.9 X 10^-5. Is this anywhere near correct? Please explain the steps if I'm incorrect. Thank you for the help.

Your method is correct but your power of 10 is wrong.

Thank you. I rechecked my problem. Should the power be positive? Or is it another power instead?
