The speed of light slows in water.
The direction of a water wave typically changes when it passes from deep to shallow water. In shallow water, the wave tends to bend and align itself more with the underwater contours due to the decrease in wave speed and change in wave refraction. This can result in the wave crest aligning more parallel to the shoreline.
As a wave passes through the boundary between air and water, the wave undergoes refraction due to the difference in wave speed between the two mediums. This causes the wave to change direction and bend towards the normal. Additionally, some of the wave's energy is reflected back into the original medium, leading to a partial reflection.
When a water wave passes, a buoy will move up and down in a circular motion. The buoy follows the wave pattern, rising as the wave crest passes and sinking as the wave trough passes. This motion is a combination of vertical and horizontal movement as the wave energy is transferred to the buoy.
That's correct. Refraction occurs when a wave changes direction as it passes from one medium to another due to changes in its speed. In this case, the change in wave speed as it moves from deep water to shallow water causes the wave to bend as it approaches the point of land.
When a wave passes through water, the water molecules themselves do not move horizontally with the wave. Instead, they move in a circular orbital motion as the wave passes, causing the up and down motion we see on the surface. The energy of the wave is what propagates through the water, not the actual water molecules moving in the direction of the wave.

Yes, wave crests tend to bend or refract as they move into shallow water due to the change in wave speed caused by the decrease in water depth. This bending phenomenon causes the wave crests to become more parallel to the shoreline.
As a water wave passes through, the particles of water move in a circular motion. Each particle of water moves in a circular path, where it oscillates up and down as the wave passes by. This circular motion helps transfer the energy of the wave through the water.
Water molecules move in an elliptical orbit as a wave passes through them. As the wave passes, the water molecules return to their original position, with no net movement in the direction of the wave. The energy of the wave is what propagates through the water, not the water itself.
Refraction is the change in direction of a wave as it passes from one medium to another. This change occurs because the wave changes speed when it moves from one medium to another, causing it to bend.
As the wave passes through, water particles move in an orbital motion. The particles move in a circular pattern, with the energy of the wave being transferred horizontally as the wave travels. This orbital motion causes the water to rise and fall as the wave passes through.
The buoy moves up and down as the water passes beneath it.
