At any moment, 50% of the earth is lighted by the direct rays of the sun,and the other 50% of the earth is not.Over the course of a year, every point on earth is lighted by the direct raysof the sun for exactly 50% of the time, and not lighted by the direct rays ofthe sun for the other 50% of the time.There is no place on earth that is always lighted by the direct rays of the sun, andthere is no place on earth that is never lighted by the direct rays of the sun.Has the questioner ever noticed it getting dark outside his home ???
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
Yes, the sun emits rays of electromagnetic radiation, including visible light, ultraviolet light, and infrared light. These rays travel through space and reach Earth, providing heat and light to support life on our planet.
The average distance from the sun to the Earth is about 93 million miles (150 million kilometers). The sun's rays travel this distance through the vacuum of space to reach the Earth and provide light and heat.
Energy from the sun reaches the Earth through electromagnetic radiation, primarily in the form of visible light. This light travels through the vacuum of space and reaches the Earth's atmosphere, where it is absorbed and converted into heat energy.
Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.
It changes the speed of the rays
If light rays did not travel through space there would be no way for them to reach Earth.
Light rays travel in straight lines called rays or beams. They propagate by transferring energy and momentum through particles or fields, such as photons in a vacuum or electromagnetic waves in a medium. Light rays can be reflected, refracted, or absorbed when interacting with different materials.

Yes, they travel some fast!
Light rays can travel through air, vacuum, and transparent materials such as glass or water. These materials allow the propagation of light by allowing the rays to pass through with little to no absorption or reflection.
Light rays travel in a straight line unless they are refracted or reflected by a medium. This straight path is known as rectilinear propagation. Light rays can also be bent when passing through different mediums with varying optical densities.
The material through which light travels can affect the speed and direction of the light rays. This is due to properties such as the density and composition of the material, which can cause refraction, reflection, absorption, or scattering of the light rays.
scattering
Radiation can come from many sources but all sources that produce radiation do so because of an abundance of energy that they possess. If you want to produce radiation light a candle. The only energy you will need to do this is a lighted match. When you light the candle wick it burns wax from the candle. This wax is stored energy that you have released as radiation in the form of light. I hope this answer is not too trite. gravity guru.
Light rays travel in straight lines due to the principle of the shortest path, known as Fermat's principle. Light travels along the path that minimizes the time it takes to travel from one point to another. This results in light rays following straight lines in a uniform medium.
