Does your body emit radio waves?
Our eyes cannot sense radio waves. Although radio waves, visible light waves, X-rays and gamme rays are all part of the Electromagnetic Spectrum, our eyes are only equipped to detect the part of the spectrum known as visible light.
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.
Where do radio waves occur?
They're found everywhere. When you consider that radio waves are sent out by every radio or TV station, every police or fire walkie-talkie, taxicab dispatcher, Bluetooth device, cordless telephone, garage door opener, cellphone, and smartphone in the world, you start to realize that no matter where you are, the room you're sitting in right now is bathed in the radio waves from a million sources or more.
What is radio control room?
Remote Control.
What is the basic radio principle?
The basic radio principle is: -- Electromagnetic waves at a desired wavelength can be generated and radiated, easily, cheaply, and continuously. -- Information can be added to the electromagnetic waves, easily and cheaply. -- The electromagnetic waves can be detected, reliably, easily, and cheaply, at a useful distance from the place where they were generated -- The waves can be easily and cheaply separated from all other electromagnetic waves that have different wavelengths. -- The information impressed on the waves can be reliably, easily, and cheaply recovered.
Can WiFi get connect to laptop in fully sealed room from outside?
Yes, as long as the walls are not to thick, or made or special materials that reflect radio waves.
Which is quieter a room hung with curtains or one with bare concrete walls why?
Curtains help absorb sound waves, whereas sound waves bounce off solid walls, so a curtained room will be more quiet.

What happens to energy in sound waves when a sound in the room fades out?
The vibrations in the air (sound) get absorbed by the walls.

How do you get echo?
Sound waves travel in airThey bounce off of pretty much everythingIn an empty room they bounce off walls and create a echo
What if your room door is transparent?
good bye
How do surfaces in a room affect loudness eg carpeted rooms vs lino rooms?
Yes! If the walls/floors are solid and flat, the sound waves bounce off them easily which makes it echoy and loud. If the walls/floors aren't flat or they have carpet, the sound waves will have a harder time to bounce off them, making the room a lot quieter than if it were wooden floors or something of that kind. :) Hope this helps!
Can echolocation work in a sound proof room?
Yes. Echolocation works by bouncing waves off of objects. A sound proof room would not allow sound to escape but there are still walls in the room to allow a bat's echolocation to bounce off of and back to the bat.
What color are waves?
Right now, this minute, in the room where you're sitting, in the space around you, there are radio waves from maybe 10,000 different radio transmitters, strong enough that you could tune them in and use them if you happened to have the right receiver sitting on the table in front of you. You can't see any of those radio waves. They have no color. You don't even know about the ones that are going straight into your eye right now, because they're all completely invisible.
Why can you hear someone but not see them from another room?
You can hear the people speaking because sound waves are reflected off of other objects (walls, trees, etc.). When the waves are reflected, they can still make it to your position and allow you to continue hearing the people as they walk. Sound waves bend around the corner.
