What basic law of electromagnetism explain how an antenna picks up a radio signal?
RF energy is transmitted through an electromagnetic field. Once the field meets the receiving antenna, voltages are produced by using the antenna as a conductor. RF voltages induced by the antenna are passed on to the receiver then reconverted to transmitted RF information.
What sre sound waves?
Sound waves are longitudinal vibrations through matter that ears can pick up as sound.
How antenna radiate em waves?
The underlying electromagnetic radiation mechanism is illustrated by evaluating the scattered radiated field and its effects on the aperture efficiency by considering the theoretical limits of a radiating conical horn with infinite length
What are two types of energy that travel in waves?
Take your pick: water waves, sound waves, electromagnetic waves, gravitational waves.
Examples of the application of interfrence of sound waves?
Since the two waves 180 degrees out of phase cancel each other you can use interference for noise dampening. Pick up the sound and generate a signal that cancels it.
What does a radio need to pick up radio waves?
antenna
Will any radio antenna pick up ultrasound?
No, radio antennas only pick up electromagnetic waves. Ultrasound is mechanical pressure waves, you need a microphone to pick them up.
Why antenna of walky talky vertical in position?
The antenna of walky talkies are vertical when in position, so to better pick up radio waves more accurately.
How does waves in the air get to a radio?
They are picked up by the antenna.

What is used to pick up radio waves?

Can a uhf antenna pick up vhf signals as well?
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.
How can radio waves convers to electrical energy?
An antenna picks up radio waves and converts them to electrical current
How do you replace an antenna on a Mazda B2200 pick up?
very carefully
What is the purpose of a cellular phone antenna?
Antennas are needed to pick up frequency signal waves in the air
Your VW Passat stereo will not pick up any radio stations?
Your VW Passat stereo will not pick up any radio stations if the antenna has come loose. The retractable antenna may also be stuck in the down position which severely limits its ability to pick up stations.
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
