What is the travel speed of television waves?
The speed of television waves is exactly the same as the speed of FM radio, heat, infrared light, green light, purple light, ultraviolet light, microwaves, x-rays, AM radio, bluetooth signals, taxi radio, garage-door-opener waves, and gamma ray waves ... because all of these waves are the same thing. The speed is 299,792,458 meters per second, or 186,282 miles per second. ADDED: It may help to realise the television is simply a special form of the radio.
Is remote control the same as radio control?
Not usually, remote control may be via wires, hydraulic, radio waves or smoke signals, Radio control refers specificaly to items controlled by radio.
Can waves carry viruses?
Waves coming into a beach may carry human viruses but the risk is low. Radio waves received by a radio receiver will not carry viruses that you could catch. Wireless communication used by computers should not carry viruses if the communication (radio waves) system is properly set up.
Harmful effects of radio waves?
Radio waves aren't harmful at its usual pattern of operation. They are harmful only when a strong signal is close to a person. It can cause cancer and other problems. Radio waves may also cure. All waves have different results.
Can radio waves travel through glass?
Yes, radio waves are a form of electro magnetic wave. Visible light is also a form of electro magnetic waves. Visible light can be seen through glass, just as radio waves can travel through glass.
What are the waves with the longest wavelengths in the electromagnetic?
ELF radio waves or extremely low frequency radio waves. These may have frequencies below 1 Hz in some cases!
What transverse wave may be AM or FM?
AM and FM are modulation types, that can probably be used for different kind of waves; but they are usually applied to radio waves. Radio waves are a kind of electromagnetic waves.
How is energy wasted by the radio?
A radio , when operating may give off a little' heat'. This is wasted energy. We don't want heat from a radio , we want 'sound'.
Which may not be a medium technology for a wireless LAN?
radio waves

How modulation work in creating radio waves?
Modulation doesn't create radio waves. After a radio wave has been created by an "oscillator" circuit, modulation may be used to add information to it, in some way that someone else will understand when he receives the radio signal and will be able to recover the information with which it's been modulated.
Can radio waves travel through glass?
Yes, radio waves are a form of electro magnetic wave. Visible light is also a form of electro magnetic waves. Visible light can be seen through glass, just as radio waves can travel through glass.

What is the working principle of rectenna?
rectenna is nothing but RECTifying anTENNA and this converts radio waves to electricity.the radio waves may be anything such as microwaves etc., by what does this rectenna works? this is only through the mesh of diodes and dipoles
