The sky does not go from total darkness to day light at sunrise nor does in go from dayligh t to total darkness at the instant of sunset. Refraction of sunlight in the atmosphere gives a period of light at dawn and dusk which affects the length of the daylight hours.
Refraction of light does not directly affect the length of the day. The length of the day is primarily determined by the tilt of Earth's axis and its orbit around the Sun. Refraction of light can affect how early we see the Sun rise and how late we see it set, but it does not change the total amount of daylight hours in a day.

How refraction of light elongates the length of day?
When light enters the Earth's atmosphere at an angle, refraction causes the light to curve slightly. This bending effect can make the Sun appear higher than it actually is, leading to an elongation of the day, especially at sunrise and sunset. This phenomenon is more pronounced near the horizon due to the larger path length through the atmosphere.
How does the speed of light have to do with the length of the day?
The speed of light is constant and does not directly affect the length of the day. The length of a day is determined by the time it takes for the Earth to complete one full rotation on its axis, which is approximately 24 hours. This rotation period is independent of the speed of light.
Why does the length of day vary from one planet to another?
Because different planets have different diameters and spin at different rates.
What contains light-sensitive cells that changes length of days and nights?
Nothing can change the length of day and night except the normal seasonal progression.
Length of a school day in 1940 in America?
In 1940, the typical school day in America was around 9:00 AM to 3:00 PM, lasting about six hours. However, the exact length of the school day could vary between schools and regions.

Why does the length of day light changes from day to day as it revolve around the sun?
due to elliptical shape of earth,the size of days and night are vary
Which explains why sky appears blue on a sunny day?
Due to refraction of light.
How do you use the word refract in a sentence?
Light rays refract when they pass through different mediums.

Does length of day light affect roosters being fertile?
no
Why do distant objects ripple on a hot day?
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.
What causes rotation and revolution?
Length of the day, Direction of sunrise, and change from light and day.
Does the length of day light change every 7 days?
No. It changes every day.
How much light should you let get into your eye a day?
A length of 500 m a day maximum
Why does the length of the day and night vary from planet to planet?
Because of the difference in speed of rotation of each planet.
How many hours of light are there in a day?
The length of the day varies depending depending on latitude and season (Winter, Fall, etc.)
