The two types of ultraviolet (UV) rays that penetrate the Earth's atmosphere are UVA and UVB rays. UVA rays have a longer wavelength and can penetrate deeper into the skin, contributing to skin aging and some types of skin cancer. UVB rays have a shorter wavelength and are responsible for causing sunburn and playing a significant role in the development of skin cancer. While UVC rays are the most harmful, they are mostly absorbed by the ozone layer and do not reach the Earth's surface.
What else can I help you with?
What are the gases called that are around earth?
Answer: An atmosphere.
What are the 2 most important elements in the atmosphere?
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
What layer will you encounter a pressure of 2 atmosphere?
You will encounter a pressure of 2 atmospheres in the ocean at a depth of approximately 20 meters (about 66 feet). This is due to the fact that pressure increases by about 1 atmosphere for every 10 meters of water depth. Therefore, at 20 meters, the pressure from the water column adds an additional atmosphere to the 1 atmosphere of pressure at sea level, resulting in a total of 2 atmospheres.
Darker lenses on sunglasses offer better protection from ultraviolet rays than do lighter sunglass lenses?
darker lens' are mostly for look and will block out more visible light but not the harmful UV rays. if u want glasses that will offer good protection check to see if they are polarized this is the best possible eye protection.answer 2 In rare circumstances, the intensity of the UV light may be instantly damaging. For example the light from an arc welder. In this case, very dark lenses are needed. For ordinary levels of UV, then a yellow or orange lens will effectively block UV rays. Have you seen the orange shades the folk on CSI use when they need to use a UV light source?
What types of radiations are there?
There are only two types of radiation. 1. Electromagnetic Under this we have gamma radiation, X radiation, light and heat 2. Particle radiation Under this we have alpha and beta.
Which forms of radiation are never able to penetrate the Earth's atmosphere?
The major types of radiation are: 1. alpha particles, which are free electrons. 2. beta particles, which are the nuclei of helium atoms 3. gamma rays, which are high-energy electromagnetic radiation like sunlight or X-rays. Alpha and Beta particles are deflected and absorbed by the atmosphere.
When was the shielding of earth from ultraviolet rays?
The ozone layer began shielding Earth from ultraviolet rays approximately 2 billion years ago when oxygen levels in the atmosphere increased due to the rise of photosynthetic organisms. The ozone layer helps to absorb the majority of the Sun's harmful UV radiation, protecting life on Earth from its damaging effects.
Does ultraviolet rays cause sunburns?
There are 2 types of ultra violet rays, UVA and UVB. UVA causes aging and wrinkles, and UVB causes the sun burns.
What are the 7 parts of the electromagnetic spectrum?
radio and TV, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays
What are the 2 important results of the formation of the ozone in the atmosphere?
The two important results of ozone formation in the atmosphere are: Ozone layer protection: Ozone absorbs and blocks a significant portion of the sun's harmful ultraviolet (UV) radiation, protecting life on Earth from its harmful effects. Climate regulation: Ozone plays a role in regulating the Earth's temperature by interacting with other greenhouse gases, influencing the Earth's climate system.
Types of radiant energy in order of their wavelengths?
Longest to shortest 1)radio waves 2)microwaves 3)visible light 4)ultraviolet radiation 5)infrared radiation 6)x-rays 7)gamma rays
What type of waves cause suntan and sunburn?
UVB rays cause sunburn to skin and massage the affected area with aloe vera gel for 2-3 minutes and leave for 15 minutes, than rinse off. Do this twice a day. It is a proven remedy to treat sunburn.
What electromagnetic spectrum is used to sterilize medical instruments?
gamma wavesUltraviolet Radiation for A+ usersultraviolet radiationAnswer #1:Gamma radiation======================Answer #2:That might be desirable, as it would kill them bugs dead in an instant.Sadly, though, we don't have any method of generating, handling, orcontrolling gamma rays easily, and they're dangerous to have around.We do those tasks with plain old ultraviolet light.
What is the major cause of coral reef distraction?
i hope you mean DESTRUCTION because that is what my answer is going to be about. 1.the loss of ozone hole allows harmful UV rays to penetrate the earth's atmosphere. this kills the microscopic algae which gives nutrition and color to the corals. 2.storm damage 3.sediment run-off
What is the difference between alpha beta gamma rays?
Alpha rays are helium nuclei (two protons + two neutrons) and have a charge of +2; beta rays are either electrons or anti-electrons (positrons), with a charge of -1 or +1; gamma rays are high-energy light rays (photons).
What can gamma rays penetrate?
Pretty much anything, it would take a few metres depth of lead or some equally dense material to stop it.
What ype of radiation ionzing is less penetrating?
1. Alpha Particles are the least penetrating, but do a great deal of radiation damage on the surface of what they hit.2. Beta Particles penetrate to a certain extent depending on their energy.3. Gamma Rays penetrate the most, and a Gamma source requires heavy (lead, etc.) shielding.
