"Microwaves" are radio waves ... those with wavelengths of 10 centimeters or less.
The wavelengths of the signals used for point-to-point microwave communication
are shorter than the wavelengths of the signals used to broadcast radio and TV to
household and automotive receivers, and also longer than the wavelength of the
signals to the GPS receiver in your car.
Microwaves are shorter than the wavelengths used to operate your cellphone.
The microwave range of frequencies (wavelengths) is used for the signals that bring
900 channels of satellite TV directly to the little dish on the corner of your house.
Here's an interesting factoid: Technically, the box in your kitchen that heats the
leftover meatloaf in 13 seconds is not a "microwave" oven. "Microwave" officially
refers to frequencies of 3 GHz and higher (wavelength 10 cm and less). The handy
kitchen appliance operates at the frequency assigned to it, which in the USA is
2.450 GHz (12.24 cm).
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Radio waves have the longest wavelength in the electromagnetic spectrum.
The electromagnetic waves with the longest wavelength are called radio waves.
No. In the visible portion of the electromagnetic spectrum, the waves at the red end have the longest wavelength (lowest frequency), and those at the violet end have the shortest wavelength (highest frequency).
Red light has the second longest wavelength in the visible light spectrum, after infrared light.
There is no longest wavelength for photons. It can be arbitrarily long.
"radio waves" have longest wavelength..
-- longest wavelength -- lowest frequency
Red light has the longest wavelength.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Red is the longest wavelength of visible light
Radio waves have the longest wavelength in the electromagnetic spectrum.
The color red has the longest wavelength of any color.
Red is the longest wavelength of visible light
Red light has the longest wavelength in the visible light spectrum.
The electromagnetic waves with the longest wavelength are called radio waves.
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
