No, any bend to sunlight due to gravity would be too small to measure with a normal size protractor. Theoretically it would be possible to do so, but you'd need a huge protractor--I'm talking probably hundreds of thousands of kilometers across.
Bending upwards towards the sun and bending over towards the ant hill.
use the sun and silhoutte
it would have to be fractional the sun is not far enough
Without atmosphere, the period of daylight would be shorter, for a few reasons.Concerning the refraction of light by the atmosphere as described in the question, it has the effect ofcausing the sun to appear HIGHER than it actually is. The sun becomes visible before it actually rises,and remains visible after it has set. This lengthens the daily period of time during which the sun appearsabove the horizon.
Use a spectrometer to measure the wavelength of the light. There is a direct, but inverse correlation of the wavelength to the temperature.
Atmospheric refraction is the bending of light as it passes through the Earth's atmosphere. During sunrise and sunset, the Sun appears to be slightly above the horizon when it is actually below it due to this effect. This bending causes the Sun to be visible a few minutes before it physically rises and a few minutes after it physically sets.
It is a type of ray that travels in a straight line without bending. Eg Search light,car and motor car,disco ray,sun ray and x_ray,radioactive rays.
A planet or moon bends toward the light due to the gravitational force of the sun or star, causing its orbit to curve. This bending of the path of the planet toward the light is what keeps it in orbit around the star.
No. An A.U. is the average radius of the Earths orbit around the Sun. (which can be measured in light years or light minutes (about 8) if you want).
The distance between Pluto and the sun is so vast that it is more practical to measure it in light hours rather than traditional units like kilometers or miles. Light takes about 5.5 hours to travel from the sun to Pluto, so using light hours helps to better represent the immense scale of this distance.
A "light year" is a measure of distance, derived from "how far light can travel in one Earth year". Thus, if you shine a torch for the amount of time it takes the Earth to orbit the sun exactly once, that light would have travelled the distance of a "light year".
The sun and moon appear elliptical near the horizon due to atmospheric refraction. This bending of light causes the celestial objects to look slightly flattened when they are closer to the horizon.
