Radiation emitted from human skin reaches its peak at λ equals 940 µm how much energy is carried by one quantum of these electromagnetic waves?
Heat waves, or infrared radiation.
If you stand ten feet away from a large campfire heat is transferred to your skin how does this happen?
electromagnetic waves carry heat from the fire to your body
What are the uses of AM waves?
the uses of the waves are the little droplets on your skin
How do you use ultraviolet waves in a sentence?
You may experience sunburned skin if you allow your skin to be exposed to the ultraviolet waves that penetrate the clouds on a cloudy day. Ultraviolet waves are at the opposite end of the visible light spectrum from infrared waves. Ultraviolet (UV) waves are longer than X-rays.
What are some dangers of ultraviolet radiation?
Remember that all light is electromagnetic radiation, which includes everything in the electromagnetic spectrum from long wave radio waves to gamma waves. These waves impart their energy to charged particles via the photon, which is the carrier particle for the electromagnetic force. Ultraviolet radiation, unlike longer wavelength radiation, contains enough energy to promote electrons from lower orbitals to higher orbitals, which may cause a variety of "dangerous" results. For example, when your skin absorbs UV radiation, electrons in the atoms of your skin cells, or worse, in your DNA, are promoted and cause the molecules which contain them to become unstable. Even worse, short wavelength UV radiation may cause ionization, which results in a charged, and thus reactive, molecule. Unregulated reactivity in the body can result in diseases like cancer.
What are the dangers of being in contact with electromagnetic waves from the electromagnetic spectrum Like gamma rays and radio waves and x-rays?
the contact yo this radiations may cause skin cancer and even death.
What can electromagnet waves travel through?
they travel through virtually anything. for example electromagnetic waves travel through our skin, our hair, anything.
Radiation emitted from human skin reaches its peak at λ equals 940 µm how much energy is carried by one quantum of these electromagnetic waves?
Heat waves, or infrared radiation.
Why would your face become darker than your body?
when you go outside in a sunny day, your skin absorbs ultraviolet waves from the sun. this waves damage your skin and makes it release more pigments called "melanin". when this pigment is in your skin, your skin becomes darker. this happens only at the damaged area. your skin that is covered by your cloth is protected from the ultraviolet waves and by that, do not release any melanins and your skin stays light
If you stand ten feet away from a large campfire heat is transferred to your skin how does this happen?
electromagnetic waves carry heat from the fire to your body
What happens if you use a sun bed for to long?
Ultra Violet Lights (UV) are used in sun beds and it burns the skin causing a tan but damaging your skin at the same time. When you overuse sun beds your skin can get permanently damaged and often causes skin cancer.
What prevents the sun's ultraviolet rays from penetrating the interior of the body?
Ultraviolet rays are very short wavelength waves above even the blue waves in the electromagnetic spectrum. They are responsible for sunburns on the skin, but are stopped by the skin. When compared with the longer infrared (heat)waves below the red waves in the same spectrum which can easily penetrate the skin and physically cook the entire body given sufficient time.
Is skin electromagnetic?
Yes
Does chalk discolor your skin?
Not permanently.
How are em waves used in dentistry?
EM waves stands for Electromagnetic Waves. The EM waves used in dentistry are usually X-Rays. These electromagnetic waves go through your skin and other body tissue (don't worry it's not very harmful or bad for you). And reflect off your bones. Think of it as a camera, the X-Ray machine sends out a flash, then takes the picture. This 'picture' shows where your bones are and whats happening to them, like, are they coming out as an adult tooth? or will you need braces in a few years. That sort of thing.
What can permanently damage skin?
Sun Rays ^-^
Can sun make your skin permanently tanned?
no
