Diffraction.
Bending of light/sound as it moves from one medium to another - Refraction.
The bending of a wave around an obstacle or through an opening is called diffraction. This phenomenon occurs when the wave encounters an obstruction that is comparable in size to its wavelength, causing the wave to spread out and curve around the obstacle.
The bending of light at the edge of a material is called refraction. This phenomenon occurs due to a change in the speed of light as it travels from one medium to another with a different optical density, causing the light rays to change direction.
The term you are referring to is diffraction, which is the bending of light waves around the edge of an obstacle or aperture, causing them to spread out and create interference patterns.
When a coin is placed in a vessel, it is hidden from view due to the refraction of light as it passes through the water and hits the edge of the vessel. When water is poured into the vessel, the light refraction changes, making the coin visible from the edge by altering the path of light rays, essentially bending them so that the coin becomes visible.
Refraction is the bending of light when it passes from one medium to another medium (like from air to glass). The basis for refraction is the speed of light is slightly different in the two mediums. Diffraction is the bending of light that occurs around a sharp edge (like light passing thru a slit). The basis for diffraction is the spreading out of the wave as it passes by the sharp edge.

The opening at the edge of a forest is called a clearing. It is an area where there are few or no trees or vegetation, allowing more sunlight to reach the ground. Clearings can be natural or created by human activity.
