What is the frequency of an electromagnetic wave with a wavelength of 1.80cm?

This is a typical math question about a wave.
First you need to know the equation: c=fλ where f is frequency, c is the speed of light and λ (Greek letter lamda) is wavelength. Next, you rearrange the equation so it can solve for what you're looking for--in this case, its frequency f. Algebraically, you can obtain the equation f=c/λ
Now you can plug in the speed of light (2.99x108 meters per second) and the wavelength that is 1,000,000 meters or 1x106 meters. And solve. The answer should be 299 Hertz (or inverse seconds-- s-1)

IF that '1.8 cm' is its wavelength in vacuum.
If that's the wavelength you observed while the wave was plowing through any
material medium, then the frequency is 162/3 GHz multiplied by the refractive
index of the medium.

What does increasing the frequency of X or Gamma ray do to its wavelength?
Increasing the frequency of any electromagnetic wave ... or of any wave for that matter ... decreases its wavelength.
How are the energy and the frequency of an electromagnetic wave related?
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.
Determine the energy and wavelength of a wave with a frequency of 3.6X 1016 hertz Would this be a wave of interest to nuclear medicine?
assuming the wave is electromagnetic... the energy of a single photon of that frequency is given by the formula E=hf where E= energy of the photon h=the Planck constant f= the frequency of the photon From this the energy of the photon is the Planck constant (6.63 x10-34) multiplied by the frequency 3.6x1016 Hz. E= 23.9x10-18 Joules. The wavelength of any wave is determined by the equation wave speed = frequency x wavelength. thus, the wavelength is the wave speed divided by the frequency. since all electromagnetic waves travel at the speed of light then... wavelength = 3x108 / 3.6x1016 wavelength = 0.83x10-8 = 8.3x10-9 metres. The electromagnetic radiation corresponding to this energy and wavelength is ultraviolet radiation and may be of interest to nuclear medicine.
What kind of wave is a gamma ray?
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
The higher an electromagnetic wave frequency the lower its?
The higher the frequency, the lower the wavelength. Wavelength
What is the relationship between the frequency and the wavelength of each electromagnetic wave?
frequency x wavelength = speed of the wave. This applies to all waves, not just to electromagnetic waves.
An electromagnetic wave with a longer wavelength has a lower?
frequency
How are the different types of electromagnetic wave organized?
By frequency on the electromagnetic spectrum
What is the wavelength of 300MHz electromagnetic wave in free space?
Wavelength = 1/Frequency
The speed of an electromagnetic wave is equal to the product of its wavelength and its?
frequency
What determines the color of a electromagnetic light wave?
Its wavelength/frequency.
What does increasing the frequency of X or Gamma ray do to its wavelength?
Increasing the frequency of any electromagnetic wave ... or of any wave for that matter ... decreases its wavelength.
Is it true that The higher the frequency of the electromagnetic wave the shorter its wavelength?
Yes. The product of the frequency and the wavelength is the speed of the wave.
How are wavelenghth and frequency of electromagnetic radiation related?
For any wave, (wavelength) times (frequency) = (speed of propagation).For electromagnetic waves, (wavelength) times (frequency) = (speed of 'light')
What is the relationship between the frequency and wavelength of electromagnetic waves?
The product of (wavelength) times (frequency) is equal to the speed of the wave.
What happens to the frequency when the wavelength of an electromagnetic wave goes up?
As wavelength goes up, the frequency comes down.
