What is another word for light waves?
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
How do microphones detect sound?
Microphones detect sound by converting acoustic waves into electrical signals. This is usually accomplished by a diaphragm that moves in response to sound waves, which then causes a coil or capacitor to generate an electrical signal corresponding to the sound received.
How EMR waves are produced?
EM waves are produced when charged particles undergo acceleration. This acceleration causes the particles to generate oscillating electric and magnetic fields, which propagate as electromagnetic waves. These waves can vary in frequency, from radio waves to gamma rays, depending on the source and type of acceleration involved.
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
How did heinrich hertz show waves acting as particles?
No. He was content to be able to generate radio waves and then detect them all the way across the room.
What is the tiny section of medium energy waves from the EM spectrum that the Human eye can detect called?
It is called visible light.

Do waves of the electromagnetic spectrum have the same frequencey?
We generate and detect electromagnetic waves that have frequenciesbetween 15 KHz and 300 GHz for a huge number of different purposes.In addition to the ones we're able to generate, other electromagnetic waves occurin nature, with frequencies up to 3,000,000,000,000,000,000 GHz.
What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
What home appliances use electromagnetic waves?
Microwaves. They give off microwaves! Also light bulbs (visible EM), heating coils (infra-red EM), and ovens (infra-red EM). Also radios and TVs receive radio waves, garage-door openers generate and transmit radio waves, blow-driers irradiate the air passing through them with infrared (heat) waves, smart and dumb cellphones all send and receive radio waves, laptops on wireless home wi-fi send and receive radio waves, and their screens generate and radiate visible light waves which make it a lot easier for us to see what they're computing.
What parts of the em spectrum can the arecibo telescope detect?
The Arecibo telescope can detect radio waves in the electromagnetic spectrum. It operates at radio frequencies between 300 MHz to 10 GHz, allowing it to study objects such as pulsars, galaxies, and the Earth's atmosphere.
Who made radios in 1895?
In 1895, any devices to generate and detect radio waves were found only in Physics laboratories. No 'radios' were manufactured or sold. Nobody really missed it, since there were no good shows on to listen to yet.
How EMR waves are produced?
EM waves are produced when charged particles undergo acceleration. This acceleration causes the particles to generate oscillating electric and magnetic fields, which propagate as electromagnetic waves.

What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
Which EM waves have the longest wavelenghts?
Radio waves
