A microwave oven operates at 2.90 GHz . What is the wavelength of the radiation produced by this appliance?
(Express the wavelength numerically in nanometers.)What is the wavelength of the radiation produced by this appliance?
c = frequency * wavelength
3.00 * 10^8 m/s = (2.90*10^9 Hz) * (wavelength)
wavelength = 0.103 meters
0.103 meters * (1.00*10^9 nanometers / 1 meter) = 1.03*10^8 nanometers is the answer.

What is the probability of the radiation arrive in the American Continent?
What is the probability of the radiation arrive in Americas, specially in south countries like Argentina and Brazil?
Here, in Brazil, we will also have a great numbers of japonese descendents that will return back from japan. I think that many of them will have problem of radiactive contamination. Brazilian descendents living in Japan are arround 250,000.What is the probability of the radiation arrive in the American Continent?
Well, I'm not so worried about the nuclear mushroom cloud affecting me as I am about it affecting the animals in Japan, and I fully expect to see a ten-story-tall lizard stomping all over Tokyo any day now.
I mean, think about it, isn't this EXACTLY how all those old black %26amp; white monster movies start, with a mysterious release of nuclear radiation and then, next thing you know, giant dinosaurs and giant moths are crushing Tokyo with their huge feet and crushing people and cars like little toys... well, isn't it?
Yuh, huh, you KNOW I'm right!! (See links, below.)

What is the frequency of electromagnetic radiation that has a wavelength of 1.51 x 10-8 meters?
What is the frequency of electromagnetic radiation that has a wavelength of 1.51 x 10-8 meters?What is the frequency of electromagnetic radiation that has a wavelength of 1.51 x 10-8 meters?
use
speed=wavelength*frequency
frequency=3*10^8/1.51*10^-8
=1.99*10^16 HzWhat is the frequency of electromagnetic radiation that has a wavelength of 1.51 x 10-8 meters?
speed of light/wavelength=frequency
Speed of light is about 3*10^8 m/s, so frequency here would be about 2*10^16 s^-1.What is the frequency of electromagnetic radiation that has a wavelength of 1.51 x 10-8 meters?
divide the wavelength by the speed of light.
19.853805165562916 PHz
From the nastier end of the UV spectrum.

What exactly is radiation, and how can it affect you?
I know what radiation is, waves like Gamma and beta, energy etc., but what exactly is it? (such as the radiation given off by Uranium, etc.) and how would it affect you if you were in a situation like the search and rescue team at the Sl-1 accident in Idaho in 1961? just super curious =DWhat exactly is radiation, and how can it affect you?
Radiation is found in 3 forms
Alpha: Helium atoms. The most dangerous, but easiest to stop. A paper stops most A-particles.
Beta: Electrons. The middle. Somewhat dangerous but also stopped quite simply. A wooden board is enough.
Gamma: Pure energy. Very difficult to stop, but also not very harmful unless in extreme amounts.
The thing that Alpha and Beta rays do is that they go into your body and shatter your DNA structure, leading to extreme amounts Cancer or/and burn damage.
I do not know the exact effect of Gammarays on the body.
Radiation is the movement of heat energy from the sun. It is a process where the radiation from the sun (infra-red rays) is absorbed or reflected by objects.
There are 3 ways in which heat can move: conduction, convection and radiation.
No one is immune to radiation. In the Japanese Tsunami, it destroyed nuclear power plants that gave off radiation. People living in a 20km radius of this area had to move because they could get radiation poisoning. This could result in death after a few hours of being poisoned. Symptoms include vomiting, dizziness, weakness and other signs of losing life.What exactly is radiation, and how can it affect you?
" In general, radiation is a process where energy emitted by one body travels in a straight line through a medium or through space. Radiation comes from the sun, nuclear reactors, microwave ovens, radio antennas, X-ray machines, and power lines, to name a few. "

Note in the top right of the web page, there is also a click-on to read about the effects
radiation can have on humans.
i'm not sure to it's validity, but from what i can understand, radiation occurs as the nucleus of and atom becomes unstable. As it does it starts losing particles of harmful energy which is what we call radiation.What exactly is radiation, and how can it affect you?
Gamma radiation can cause genetic mutations which lead to cancer.

What is the frequency of this radiation?
An argon ion laser emits light at 489nm. What is the frequency of this radiation? Is the emission in the visible spectrum? If yes, what color is it?What is the frequency of this radiation?
frequency = c/wavelength
here c is the speed of light in vacuum, a constant (3*10^8 m/s). Now, don't forget to convert nm to m before you do the calculations! Also, remember that the SI unit of frequency is Hz (1/s).What is the frequency of this radiation?

What is the intensity of EM radiation in this region?
Two incoherent EM waves of intensities 9 and 13 travel in the same direction in the same region of space. What is the intensity of EM radiation in this region?
I tried 44 and then 0.37 and they were wrong, please help.
*I give 10 points to best answers so try answering my unresolved questions!What is the intensity of EM radiation in this region?
Because the waves are incoherent, the intensities simply add (being incoherent, they cannot interfere), so the time-averaged intensity of the radiation in the region of interest would be 22 ( = 9+13).
