What is an electromagnetic wave?
100
A vibration of electrical and magnetic fields that move through space at the speed of light.
What is an electromagnetic wave?
100
All electromagnetic waves travel at the same speed in a vacuum, but they have different wavelengtns and different frequencies.
What is speed=wavelength x frequency?
100
Incandescent, tungsten-halogen, fluorescent, vapor, and neon lights
What is the common types of light bulbs?
100
Transmission antennas send out, or broadcast, radio waves in all directions. Radio waves carry information from the antenna of a broadcasting station to the receiving antenna of a radio or television.
What is radio waves?
200
Light and other electromagnetic waves.
What is produced by charged particles?
200
The energy that is transferred through space by electromagnetic waves.
What is electromagnetic radiation?
200
Radio waves, infrared rays, visible light, ultraviolet rays, and gamma rays
What is the electromagnetic spectrum made of?
200
An object is illuminated if you see it by reflected light.
What is illuminated?
200
Amplitude modulation and frequency modulation.
What is the two methods of transmitting signals?
300
The electromagnetic spectrum.
What is the complete range of electromagnetic waves in order to increasing the frequency?
300
Exerted magnetic forces that can act on certain materials.
What is an magnetic field?
300
The electromagnetic waves with the longest wavelengths and lowest frequencies. They include broadcast waves (for radio and television) and microwaves.
What is radio waves?
300
An object is luminous if it gives off its own light.
What is luminous?
300
A method of transmitting signals by changing the amplitude of a wave.
What is amplitude modulation (AM)?
400
The electric field will be changed as well.
What is the cause of a magnetic field being changed?
400
Produce electric forces that can push or pull on other charged particles.
What is an electric field?
400
The distance between two corresponding parts of a wave.
What is a wavelength?
400
A light bulb that glows when a filament inside it gets white hot. Different types are ordinary and tungsten-halogen light bulbs.
What is an incandescent light and the type of bulbs?
400
A method of transmitting signals by changing the frequency of a wave.
What is frequency modulation (FM)?
500
An magnetic field
What is produced when a charged particle moves?
500
The properties of electromagnetic waves are explained by a wave model.
What is the properties of electromagnetic waves?
500
The electromagnetic waves with the shortest wavelengths and highest frequencies.
What is gamma rays?
500
Some spaces lit by fluorescent lights. Streets and parking lots lit with vapor lights. Neon lights are often the flashy attractive lights. Different types are fluorescent, vapor, and neon lights.
What is other light sources and different types?
500
Radio, television, and telephone signals and relay the signals back to receivers on Earth.
What is the receivers to communication satellites and transmission?
