Question

A hurricane generates waves at Bermuda 800 km south-east of Rhode Island. Two sets of waves are generated with the periods of 8 seconds and 12 seconds. Assume the ocean has an average depth of 3000m.

How long does it take for the 8 second waves and the 12 second waves to arrive in Rhode Island, respectively?

What are their wavelengths? Wave numbers?

What would be your answer to part a and b if we assume the ocean is 20m deep instead of 3000m?
