In distant vision, the degree of light refraction is generally decreased. This is because parallel rays of light from distant objects require less bending to focus on the retina compared to closer objects. The eye's lens flattens to accommodate this, resulting in less refraction needed for distant vision.
decreased
The degree of refraction is directly proportional to the frequency of the wave. This means that as the frequency of the wave increases, the degree of refraction also increases. This relationship is described by Snell's Law in optics.
Distance objects can be seen to "ripple" on a hot day because of refraction. As light from a distance object makes the trip to the observer, it passes through air of slightly varying densities. This causes it to "change course" to a degree, which is refraction. It is this thermally induced refraction that is responsible for the "ripple" we see, and for the mirage we sometimes hear about.

During close vision, the degree of light refraction increases as the eye accommodates to focus on near objects. The ciliary muscles contract to increase the curvature of the lens, allowing for better focus on nearby objects.
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
The angle of incidence affects the degree of bending of light in a semicircular prism by determining the angle of refraction as the light enters and exits the prism. A larger angle of incidence will result in a greater angle of refraction, causing the light to bend more as it passes through the prism. The relationship between the angle of incidence and the angle of refraction is determined by Snell's Law.
When a wave enters a new medium at a 90-degree angle, it doesn't change its direction because the boundary between the two media is behaving like a mirror, reflecting the wave back with no refraction. Refraction occurs when the wave enters the new medium at an angle other than 90 degrees, causing it to change speed and direction.
Being thirsty is a brain response due to increased blood osmolarity or decreased blood volume. The human body must keep its blood osmolarity close to 300 mOsms in order to function properly. If it is increased or the blood volume is decreased the brain will release hormones such as ADH(antidiuretic hormone- to save water) and will trigger a thirst response in the brain. Soft-drinks as opposed to water, have an increased osmolarity and therefore cannot lower your blood osmolarity to the same degree as water and therefore do not relieve your thirst. Hope that helps
Yes, temperature is a measure of the average kinetic energy of the particles in an object. Higher temperatures indicate increased particle motion and typically correlate with a sensation of hotness, while lower temperatures indicate decreased particle motion and correlate with a sensation of coldness.

When light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence, it continues in a straight path without bending. This is due to the fact that there is no change in the speed of light when the angle of incidence is 0 degrees.
