Super refraction is an atmospheric bending of radio waves that causes them to follow the curvature of the Earth more closely than normal, resulting in an increase in signal strength at a receiver beyond the normal line of sight range. This phenomenon can occur due to temperature inversions in the atmosphere.

What are the meteorological causes of super-refraction in the troposphere?
Refraction in the atmosphere usually refers to the gradual vertical deflection of light or radio, because of a vertical gradient of refractive index with altitude. The gradient is usually negative with altitude, so light and radio usually curve downward at various rates, depending on the magnitude of the gradient. "Super-refraction" is the label given to the condition wherein the gradient is so steep that light and radio curve downward along their path more rapidly than the surface of the earth does, so that the altitude of an initially-horizontal beam progressively decreases. Refraction is more pronounced as the temperature increases and humidity decreases more rapidly with altitude. Super-refraction results when the combined effect of these two parameters reaches a specific value.
What is it called when a wave goes from one medium to another and it changes speed and direction?
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
What do you called when the light bends as it enters a different medium the process is known as?
The process of light bending as it enters a different medium is known as refraction. Refraction occurs because light changes speed when it travels from one medium to another, causing the light wave to bend.
When was Super Refraction created?
Super Refraction was created in 1997.

Imagine that you are a fish underwater When you look up to the surface to the water you can see the sky and also the bottom of the pool How do you explain this unusual view?
Reflection and refraction. You see the reflection on the bottom of the surface of the pool. You see the refraction of light through the surface of the pool. This is the super short answer...someone else might provide more information but the reader can "google" reflection and refraction to find out more.

What is it called when a seismic wave bends as it passes from liquid to solid rock.?
it is called refraction
How does refraction affect the appearance of the sky?
The sky is blue because of refraction. Sunsets and sunrise are so beautiful because of refraction. If there was no refraction, we would see the sky as a black expanse.
