Physics help please!

The speed of a deep water wave with a wavelength ë is given approximately by v = (gë/2ð)1/2. Find the speed and frequency of a deep water wave with a wavelength of 5.5 m.
? m/s
? Hz

can someone get me started with a formula? I lost my book :(

    okay for a) I got the answer as 11.67 seconds and did v=d/t and for b) i found that wavelength= 6km. Im confused how the 100 m deep affects the equation for c and d. The 2011 Japan tsunami was triggered by an earthquake 70 km
