There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).

What is the emission wavelength equation used to calculate the specific wavelength of light emitted by a substance?
The emission wavelength equation used to calculate the specific wavelength of light emitted by a substance is c / , where represents the wavelength, c is the speed of light in a vacuum, and is the frequency of the light emitted.
What measures the exact frequency of the light emitted when an electron changes levels?
Spectrometer is used to measure the exact frequency of the light emitted when an electron changes levels. It separates the different wavelengths of light to determine their frequencies accurately.
Which allows you to calculate the energy of the emitted light What is the value of the constant needed to complete this equation?
To calculate the energy of emitted light, you can use the equation E = hν, where E is energy, h is Planck's constant (6.626 x 10^-34 Js), and ν is the frequency of light. The value of the constant, Planck's constant, is 6.626 x 10^-34 Joulesseconds.
What is the process to calculate the energy difference for the electron transition in a given system?
To calculate the energy difference for an electron transition in a system, you can use the formula E hf, where E is the energy difference, h is Planck's constant, and f is the frequency of the transition. This formula relates the energy of the transition to the frequency of the light emitted or absorbed during the transition.

How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.
Why can astronomers use the speed of light to calculate distances?
Because visible light is emitted at a known frequency (a time) and then it is as simple as Speed = Distance / Time therefore Distance = Speed x Time.

Calculate the wavelength (in nm) of the blue light emitted by a mercury lamp with a frequency of 6.88 1014 Hz.?
To calculate the wavelength of the blue light emitted by the mercury lamp, use the formula: wavelength = speed of light / frequency. The speed of light is approximately 3.00 x 10^8 m/s. Convert Hz to s^-1 by dividing by 1/s. Then, plug the values into the formula to find the wavelength in meters, which can be converted to nanometers by multiplying by 10^9.
How can we calculate the wavelength of the photon emitted in a given scenario?
To calculate the wavelength of a photon emitted in a given scenario, you can use the formula: wavelength speed of light / frequency of the photon. The speed of light is approximately 3.00 x 108 meters per second. The frequency of the photon can be determined from the energy of the photon using the equation E hf, where E is the energy of the photon, h is Planck's constant (6.63 x 10-34 joule seconds), and f is the frequency of the photon. Once you have the frequency, you can plug it into the formula to find the wavelength.

If molybdenum is irradiated with light of a wavelength of 122 nm what is the maximum possible kinetic energy of the emitted electrons?
The maximum kinetic energy of the emitted electrons is calculated using the formula: (E_k = hf - \phi), where (h) is the Planck constant, (f) is the frequency of the light (speed of light/wavelength), and (\phi) is the work function of molybdenum. Given the wavelength, you can calculate the frequency, then use the work function value for molybdenum to find the maximum kinetic energy of the emitted electrons.
What is the frequency of light emitted by a laser pointer whose wave is 670 nm?
The frequency of light emitted by a laser pointer with a wavelength of 670 nm can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values, we get frequency = 3x10^8 m/s / (670x10^-9 m) = 4.48x10^14 Hz.
How is the peak frequency of emitted light related to the temperature of its incandescent source?
The peak frequency of emitted light is directly proportional to the temperature of the incandescent source, as described by Wien's displacement law. As the temperature of the source increases, the peak frequency of the emitted light shifts to higher values, resulting in a bluer appearance for higher temperatures and a redder appearance for lower temperatures.
