How does sun rays pass through the atmosphere layers?

Light requires some medium to pass through, what's the medium in the space, and How does sunrays enters into the earth.

No, it doesn't. Electromagnetic radiation consists of oscillating electric and magnetic fields, and these can exist and propagate in a vacuum.

what's the medium in the space, and How does sunrays enters into the earth.

The atmosphere is transparent at some wavelengths, and opaque at others. Transparent just means that the light waves can simply pass through the atmosphere unimpeded by the particles that are present. (They interact with these particles and are slowed by them, but their progress is not stopped entirely).

That medium used to be known as "aether", and its existence was experimentally refuted in the 19th century. Modern physical theories believe that light propagates through the space without any other media.

Light is electro-magnetic waves. If you really must have a medium, it is the electro-magnetic field which, at every point in space is the vector sum of all electric and magnetic forces from all objects in the universe.

Sun rays pass through the atmosphere layers by traveling in the form of electromagnetic radiation. The atmosphere is made up of various gases such as nitrogen, oxygen, and carbon dioxide, which act as the medium for the sun rays to pass through.

As the sun's rays enter the Earth's atmosphere, they encounter these gas molecules, which absorb and scatter the light in different directions. This process is known as scattering, and it is responsible for the blue sky we see during the day.

The Earth's atmosphere is divided into several layers, each with different properties that affect the way sun rays pass through them. The troposphere, which is the layer closest to the Earth's surface, is where most of the scattering occurs. As we move higher up in the atmosphere, the air becomes thinner, and the scattering decreases.

When the sun's rays reach the Earth's surface, they are absorbed by the land, water, and other objects. This absorption of light is what causes the Earth's surface to warm up, creating the different climates and weather patterns we experience.

In space, there is no medium for the sun's rays to pass through, as it is a vacuum. However, when the sun's rays reach the Earth's atmosphere, they interact with the gas molecules and particles present in the atmosphere, allowing them to pass through and reach the surface.

In conclusion, the sun's rays pass through the Earth's atmosphere by traveling as electromagnetic radiation and interacting with the gas molecules and particles present in the atmosphere. This process is vital for sustaining life on Earth and plays a crucial role in the Earth's climate and weather patterns.
