EM Spectrum Flashcards
What is the definition of the electromagnetic spectrum
1.A list of electromagnetic radiations
2.a list of all the types of light
What speed to all of the members of the electromagnetic spectrum travel at
3x10(8) (speed of light)
What is the difference between each of the radiations
They vary in wavelength and frequency
As the frequency of the wave increases, the wavelength…
Decreases
What is the radiation with the highest energy
Gamma
Why does gamma have the highest energy
Because it has the largest frequency. The larger the frequency of the light, the more energetic it is
What order does the electromagnetic spectrum go (in order of increasing frequency)
Radio and TV, microwaves, infrared, visible light, ultraviolet, x-rays, gamma
What is the order of the electromagnetic spectrum in order of increasing wavelength
Gamma, x-rays, ultraviolet, visible light, infrared, microwaves, radio and TV
What is a use of radio and TV waves
Communications and television
What is the detector of radio and TV waves
Aerial
What are the uses for microwaves
Communications and heating food
What is the detector for microwave
Aerial
What are the uses of infrared
Heat cameras, treating muscle injuries
What are the detectors for infrared
Photodiode, black in thermometer or photographic films
What is the use for visible light
Lasers
