What are ultraviolet rays like?

The sun is the source of energy. Along with the energy from it, the rays of light also spread all around. There are different types of light rays. The sunlight is white. But it is made up of seven colors. These seven colors are visible to the human eye, but there are also rays of color in the sun that humans cannot see. The last color we see is purple. Purple is followed by X-rays in sunlight. And then there are the ultraviolet rays. They are not visible to us.

Some insects, such as bees, can see it. Ultraviolet rays are intense. If it falls on a person's skin, it is damaged. Damage even if it enters the eyes. Between the light rays coming to the earth comes through the ozone layer. The ozone layer absorbs ultraviolet rays.

That is why ultraviolet rays rarely reach the earth. However our body also needs a few too many ultraviolet rays. Ultraviolet rays are more prevalent in the intense sunlight of a summer afternoon. Black goggles protect against these rays.

The wavelength of ultraviolet rays is shorter than normal light. There are nine types of ultraviolet rays. The most intense are the types. There is type B of medium intensity and type C of short wavelength. Near ultraviolet is the highest intensity that birds, fish etc. can see. Then the mid-range MUV. Hydrogen Lemon Alpha Ultraviolet rays have a special type of short wavelength. The last vacuum is ultraviolet and the extreme is ultraviolet. Different types of rays have different effects on the atmosphere.

Scientists have created special types of lamps to produce synthetic ultraviolet. These lamps are useful for shaking patients. Ultraviolet LEDs have also become a light source. Ultraviolet lasers are widely used in medicine. Vitamin D is formed in our skin in the presence of sunlight. So ultraviolet rays play a major role in the process.
