    Welcome to the PF. We do not do your homework/coursework for you. What are the Relevant Equations? (There's a reason we ask for those in the Homework Help Template that you deleted from your post.)

    Are any equations specified with your work? If not, have a look in your textbooks or online. When trying to pick equations to use remember what information you have and what you hope to get out of it. You only have one piece of information, the wavelength λ, perhaps there are some universal constants you can use to find your answers?
