Imagine that you are standing on a beach but cannot swim. Your friend encourages you to walk into the surf zone created by incoming deep water waves that a wavelength of 30 meters. Would it be safe to walk out to where the waves are breaking?

Explanation:

The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult

Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer

It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.
