We are always exposed to sun rays. The sun gives out radiation consisting of many different frequencies of light. The major component of light it gives off is visible light (which is why our eyes evolved to see visible light best). It also gives off infrared light, ultra violet light, and even more dangerous frequencies. Luckily, the atmosphere of earth filters out a lot of the dangerous frequencies (although not perfectly). If you stay in the sun too much without sunblock, the ultra violet light that gets through the atmosphere can lead to cancer (it's a game of probability). If you go outside of the atmosphere without protection somehow, the rays from the sun become much more dangerous. You would also be susceptable to cosmic radiation, which can lead to cancer.
Of course, the closer you get to the sun, the more concentrated the radiation will be, and the more dangerous it will be.
What else can I help you with?
What time of the year is the northern hemisphere exposed to vertical rays of the sun?
The northern hemisphere is exposed to vertical rays of the sun during the summer solstice, which occurs around June 21st. This is when the North Pole is tilted towards the sun, leading to longer daylight hours and more direct sunlight in the northern hemisphere.
Why surface exposed to sun is warmer?
I think the reason why it is warmer is because the sun's rays are hitting it directly.
How many rays are on the sun?
The sun emits countless rays of light and energy in all directions. It is impossible to determine an exact number of rays on the sun as they are constantly being emitted and are not individually distinguishable.
What is are sun rays called in the summer?
At any time of the year they are 'RADIATION'.
What harmful rays from the sun cause sunburns?
Ultraviolet rays from the Sun cause sunburns.
What word means a room or place exposed to the sun rays?
That is a solarium.
What happens to trolls when they are exposed to daylight?
They turn to stone when the are exposed in the sun
What time of the year is the northern hemisphere exposed to vertical rays of the sun?
The northern hemisphere is exposed to vertical rays of the sun during the summer solstice, which occurs around June 21st. This is when the North Pole is tilted towards the sun, leading to longer daylight hours and more direct sunlight in the northern hemisphere.
Does a dog's fur get darker when exposed to the sun?
Yes, a dog's fur can get darker when exposed to the sun due to the sun's UV rays causing the production of more melanin in the fur.
Why surface exposed to sun is warmer?
I think the reason why it is warmer is because the sun's rays are hitting it directly.
The tanning effect that occurs when a person is exposed to the sun is exposed to the sun is somewhat protective due to?
Increased production of melanin.
What happens when the stratosphere contians the ozone layer?
It protects us from UV rays. These are harmful rays of the sun.
What happens to your eyes when you see sun with your naked eyes?
As intensity of sun light rays are greater so,when we see sun with our naked eyes the sun rays falls on eye lens which is convex which diverges the rays and make it difficult to see
What happen to the molecules of the water when it is exposed to sun rays?
The temperature increase and the motion of molecules is accelerated.
Ultraviolet sun rays responsible for burning skin?
Ultraviolet (UV) sun rays, specifically UVB rays, are responsible for burning the skin and causing sunburn. When the skin is exposed to excessive UVB rays, it can lead to inflammation, redness, and blistering. It is important to protect the skin from these rays by using sunscreen and seeking shade during peak sun hours.
What happens to the energy from the suns rays that reach earth?
As the sun's rays heat up the earth, the radiation hits the atmosphere. Then the radiation heads back to the sun.
Does the sun really not cause cancer?
The sun's ultraviolet (UV) rays can cause skin cancer if a person is exposed to them for long periods without protection. It is important to use sunscreen and take other precautions when spending time in the sun to reduce the risk of skin cancer.
