Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

Part A
A scuba diver stands at the bottom of a lake that is 14 m deep.
What is the distance to the closest points at the bottom of the lake that the diver can see due to light from these points being totally reflected by the water surface?
