EM waves travel at the speed of light in a vacuum. c=f*lambda where c is the speed of light, f is the frequency of the way and lambda is the wavelength.
Lambda= c/f = (3x108 m/s)/3x1010 s-1) = 1x10-2 m or 1 cm

What has a 10 angstrom wavelength?
Lambda = wavelength = 1.0 Angstrom = 1.0 x 10-10 mf = frequencyc = speed of light (2.9979 x 108 m/s)*Use the following equation:c = lambda x f (lambda times f)*Rearrange the equation for frequency:f = c / (lambda) (c divided by lambda)= (2.99798 m/s) / (1.0 x 10-10 m/s)= [answer]
Do microwaves use microwaves?
Microwaves are radio waves with frequencies above 3 GHz. They are used to communicate great volumes of information over distances up to 100 miles, at data rates up to several hundred megabits per second per carrier. Certain high-power devices use UHF radio waves to boil water and heat meatloaf. They are marketed under the generic name "microwave ovens" and referred to as "microwaves" by the population at large, even though they use radio waves at 2.45 GHz and, technically, fall 550 MHz short of rights to the title.
What energy source does a microwave use?
They are powered by electricity of course, but the generate microwaves (an electromagnetic wave, like light - but of a higher frequency). We are surrounded by microwaves from the sun, satalites, and radiation from electrical dewvices, but microwaves concentrate the energy - heat happens where "beams" cross and excite the molecules of what they are passing through (i.e. heat).
Which types of electromagnetic waves are used for communication?
Technically all could be used for communication. Although not all may be suited for the use. Here are a few examples: Radio waves - short wave/long wave radio Microwaves - Used for communication of space objects (spacecraft, satellites, radar etc) Infra-red - Used as a wireless communication between devices like mobile phones Ultra Violet - Butterflies use two ultraviolet signals, UV reflectance or absorbance as a communication system X-Rays - High powered telescopes Dont forget fibre optics for the visible part of the spectrum.
What radio operates the frequencies of 3000 kHz and 30 MHz?
microwaveI am sorry, but the above answer of "microwave" is dead wrong! 3000 Khz = 3Mhz. 3-30 Mhz is called the HF frequency band. 3-30 Ghz (1000 times higher) is the microwave band.A lot of the worldwide Amateur "Ham" Radio bands are located on 3-30Mhz. All of the "shortwave" radio stations. The US Bureau of Standards operates on EXACT frequencies of 5.000000, 10.000000, and 20.000000 - these are also the EXACT TIME beacons that many clocks synchronize to*. There are radio beacons, jamming signals from third world countries, military radio, RTTY (basically "fax" by radio), weather satellites, CB radio, Radio Control frequencies (for RC controlled cars, planes, boats), diathermy machines (used in doctors offices), and the HAARP project in Alaska which is "supposedly" for Auroral research.*The "atomic clocks" and watches that most consumers can buy are synced to this same WWV source, but operate at 60 Khz (or 60,000 hertz). 10Khz is about the "basement" of the radio frequency bands.
What is a radio wave's relative wavelength and frequency is?
The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.
What type of wave is microwave?
"Microwave" is an electromagnetic wave, and is part of the category of radio waves.A radio wave is "microwave" when its frequency is above 3 GHz (wavelength isless than 10 centimeters).Ironically, the "microwave oven" radiates the food with high power radio wavesat a frequency of 2.5 GHz, so technically, it doesn't use 'microwave' energy at all.
What wave viabrates faster radio wave or microwaves?
Microwaves ARE radio waves, with frequencies above 3 GHz.
What type of wave has the shortest wavelength GHz or MHz?
Usually gamma radiation are among the shortest energy wavelength.
What is the frequency of light traveling in a vacuum with a wavelength of 1 mm?
Frequency = speed / wavelength = 3 x 108/0.001 = 300 GHz . (rounded)Most folks would call that a "millimeter wave" or a "darnedshort microwave", not light. It's certainly not visible.
What type of wave is a microwave?
a microwave is an electromagnetic wave.================Answer #2:A microwave is a radio wave with a wavelengthless than 10 cm (frequency greater than 3 GHz).
If wavelength is 15 nm what is the frerquency?
Frequency = (speed) / (wavelength), so it depends on the speed of the wave. If it's a light wave, then the frequency is (3 x 108) / (15 x 10-9) = 20,000,000 GHz. If it's a sound wave, then the frequency is (343) / (15 x 10-9) = 22.9 GHz.
Which wavelength is shortest 1 GHz or 100 GHz?
1 GHz
What is the speed of a microwave with 3 GHz frequency?
For any electromagnetic wave, the wavelength depends on the frequency, but the speed doesn't. They all have the same speed. It's 300 million meters per second, regardless of the frequency. The wavelength at 3 GHz is 10 centimeters.
What is the difference between microwaves and radio waves?
They are the same thing; vibrations of the electromagnetic field. Microwaves have a frequency between 0.3 GHz to 300 GHz, and radio waves have a frequency between 3 Hz to 300 GHz. So microwaves are a type of radio wave.
A wave has a frequency of 3 GHz and a speed of 3 x 108 ms what is the wavelength?
velocity.,i.e., speed = frequency X wavelength wavelength=velocity/frequency=(3X108m/s)/(3X109/s)=0.1m
What is the longest wavelength of a radio wave?
"Radio" is the name we give to a section of the electromagnetic spectrum, so it can include whatever wavelengths we decide to use that name for. Radio is generally considered to be everything in the electromagnetic spectrum with wavelengths of one millimeter or longer, corresponding to any frequency up to 300 GHz.
