Best Answer

The wave number of a photon is the spatial frequency of the photon's electromagnetic wave. It is defined as the reciprocal of the wavelength of the photon, typically measured in units of inverse meters. As the wave number increases, the wavelength decreases, and vice versa.

The x-axis of an infrared spectrum is in units of wavenumber-- wavenumber is?

wavenumber is directly proportional to energy. It is inversely proportional to wavelength. I think wavenumber has the unit of m-1


What is the wavenumber of IR radiation designated by 31.95 microns?

The wavenumber of IR radiation designated by 31.95 microns is approximately 312.88 cm^-1. Wavenumber is calculated by dividing the speed of light by the wavelength, thus converting the micrometer wavelength to cm.


How do you calculate wavelength from wavenumber?

You can calculate wavelength (λ) from wavenumber (ν) using the formula λ = 1/ν, where λ is the wavelength in meters and ν is the wavenumber in reciprocal meters (cm^-1 or m^-1).


What is the formula for determining wavelengths at which the the Stokes and anti-Stokes Raman lines would appear when wavenumber and wavelength of the laser are known?

The formula is: Wavelength of Stokes line = Wavelength of laser / (1 - wavenumber of Raman shift) Wavelength of anti-Stokes line = Wavelength of laser / (1 + wavenumber of Raman shift) Here, the wavenumber of the Raman shift is represented in reciprocal centimeters.


What is the unit for wavenumber?

The unit for wavenumber is reciprocal length, typically in units of inverse meters (m⁻¹). It is used to describe the spatial frequency of a wave in terms of how many wave cycles occur per unit distance.


What is relation between wavelength and frequency?

wavenumber= 1/wavelength


What is the units for wave number?

Wavenumber is inversely proportional to wavelength, so has units m^-1


What is the wave number of IR radiation designated by 20.48 micrometres?

Just divide 1 by the wavelength in microns, to get the wavenumber, in cycles/micron.If you want the wavenumber in cycles/meter, first convert the microns to meters, then divide 1 by this wavelength.

A packet of light energy is called a photon.


Which is more energetic a red photon or a blue photon?

The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.


How do you calculate frequency in ir spectroscopy?

In IR spectroscopy, the frequency of a vibration is related to the wavenumber, which is measured in reciprocal centimeters (cm^-1). The frequency can be calculated using the equation: frequency (Hz) = wavenumber (cm^-1) x speed of light (cm/s).


How do you calculate photon flux given v?

Photon flux can be calculated using the formula: photon flux = v * E, where v is the frequency of the photons and E is the energy of each photon. By multiplying the frequency of the photons by the energy of each photon, you can determine the photon flux.
