Suppose water waves are moving from the deep end to the shallow end of the pool. That is, the waves are moving into a medium (shallow water) where they slow down. In what direction will the waves turn slightly, and why

The wave turn slightly to the bottom.

Explanation: Because part of the wave travel faster causing the wave to turn.

If the wave is moving from deep to shallow, as the depth approaches 1/2 a wavelength, things start to change - the wave will start to rise vertically and eventually brake. You can imagine the bottom of the wave hitting the sea bottom and slowing down, the frequency will go up, the velocity of the wave will go down.

As a wave moves into shallow water, its orbitals “feel the bottom,” causing it to slow down. This end is in shallower water, so it slows down towards the shore than the slower-moving end in.

Water waves will change direction at a boundary between deep and shallowwater. The waves slow down as they enter the shallow water which causes the wavelengths to shorten.

As waves travel into the denser medium, they slow down and wavelength decreases.Part of the wave travels faster for longer causing the wave to turn.The wave is slower but the wavelength is shorter meaning frequency remains the same.

your answer would be fusion

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
