the correct answer is a:air im in plato to so
Could it be that the frequency of sound waves are to low?
The electromagnetic spectrum - is simply the range of frequencies that radio waves etc travel at. This ranges from below human hearing (sub-sonic), through audible range past supersonic, broadcast radio, terrestrial television, micro-waves, satellite and beyond !
All electromagnetic (EM) waves are in the EM spectrum. This is from "ELF" (3-30hz) through visible light (300Thz+), out past gamma rays. Any wave above DC that broadcasts into space is part of the EM spectrum.
electromagnetic- light travels in the form of waves ( visible spectrum- 380-760 nanometres)
You don't invent scientific facts - they are there for anybody to observe. You discover them. I believe Maxwell's calculations were groundbreaking in this sense; he calculated that an electromagnetic wave would move at the speed of light, and concluded that light was probably an electromagnetic wave, too. This was later confirmed. However, parts of the electromagnetic spectrum were later discovered by other scientists, for example, Röntgen.
Yes. Electromagnetic spectrum waves reach your eye through the air.
Could it be that the frequency of sound waves are to low?
The entire electromagnetic spectrum can move through a vacuum.
X-Rays
If you mean "on air" as with radio and television, mobile telephones etc., then no they do not. They are part of the electromagnetic spectrum and are transmitted through this. I suppose you could say they pollute the electromagnetic spectrum.
Light spectrum is part of the electromagnetic radiation spectrum. Electromagnetic waves travel better and faster (light speed in vacuum) in vacuum.
Sound.
Through the electromagnetic spectrum, specifically radio waves.
The electromagnetic spectrum is the range of all possible frequencies of the electromagnetic radiation. The ELECTROMAGNETIC SPECTRUM of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.The components of the electromagnetic spectrum are :a) Radio frequencyb) Microwave through far infraredc) Near infraredd) Visiblee) Ultravioletf) X Raysg) Gamma Raysh) High Energy Gamma Rays.
Yes! that's how light from the sun gets to the Earth. Electromagnetic do not require a medium to travel through, they can even travel through a complete vacuum.
Yes, infrared waves are part of the electromagnetic radiation spectrum and all electromagnetic radiation will propagate through a vacuum.
Becasue heat radiation(Infra-red) is part of the electromagnetic spectrum. All waves in the electromagnetic spectrum(e.g light, radio waves) don't need particles(mass) to carry energy.
