Bending upwards towards the sun and bending over towards the ant hill.
Yes, mirages are real and are caused by the bending of light rays due to variations in air temperature. This bending of light can create optical illusions, making distant objects appear distorted or displaced.
The two extreme variations in a are trait are favored in disruptive selection.
Refraction and diffraction are two words that describe the bending of a wave. Refraction occurs when a wave changes direction as it passes from one medium to another, while diffraction is the bending of a wave around obstacles or through openings.
The term for variations in the loudness of sound caused by wave interference is known as "beats." This phenomenon occurs when two sound waves with similar frequencies interfere with each other, creating alternating patterns of loudness and quietness.
Sound waves can refract in different mediums due to changes in the speed of sound caused by variations in temperature, pressure, and density. When a sound wave enters a medium with a different speed of sound, it can change direction, bending towards or away from the normal line, which is the imaginary line perpendicular to the interface between the two mediums. This bending of sound waves is known as refraction.
The two types of forces used when bending are compressive force, which acts to squeeze or compress the material, and tensile force, which acts to stretch or pull the material. These forces work together to deform the material into the desired shape during the bending process.
The bending of light in reflection is caused by the difference in the speed of light in the two different mediums (air and a denser material) at the interface. This change in speed leads to refraction, resulting in the bending of light rays at the boundary.

Bending a joint is a flexion movement. It decreases the angle between two body parts (such as the thigh and calf at the knee joint).
Reflection and Refraction
Refraction and Diffraction are two words that also relate to light. Refraction is the bending of light as it passes through different mediums, and diffraction is the bending of light as it passes around obstacles.
