Refraction.
light
When light is bent, it is called refraction. Refraction occurs when light travels through different mediums, such as air and water, causing it to change speed and direction. This bending of light is responsible for optical phenomena such as rainbows and the way objects appear distorted when submerged in water.
Light always travels in a straight line with respect to space-time. If it appears to the observer that the light beam has bent it can only be concluded that space-time is bent.
This is also known as "refraction".
Refraction. This is when light changes direction as it passes from one transparent medium to another with a different optical density, causing it to bend.
this might be refraction
The distance light travels in a year is called light-year
The name applied to light that is bent in the atmosphere is "refraction." This bending of light occurs due to the change in speed as light travels through different mediums with varying densities, such as air through the Earth's atmosphere.
When light travels from one medium to another, such as from air to water, it can change direction. This change in direction is called refraction. As light passes through the water and into the air inside the straw, it refracts again, causing the straw to appear bent at the water's surface.
The bouncing of light off a surface is called reflection. When a light wave is bent it is called refraction.
light is called a ray because light travels in straight lines
light is a type of energy, it travels in packets of energy called photons
