Calculating Emission Wavelength for Excited Atoms at 3.031x10^-19 J Energy Level

In summary, an emission wavelength is the specific wavelength of light emitted by an object or substance. It is directly related to the color of the object or substance, with different colors corresponding to different wavelengths. Factors such as chemical composition, temperature, and energy level can affect emission wavelengths, which are typically measured using a spectrophotometer. Emission wavelengths are important in scientific research as they can provide valuable information about the properties of a substance, such as its chemical composition and molecular structure.

λ=hc/E

I'm stuck on the first part. i.e;

something / 3.031x10^-19J

What is ##h##? what is ##c##?

If you don not know, go to "photon energy" wiki page.
 

What is the formula for calculating emission wavelength?

The formula for calculating emission wavelength is: λ = hc/E, where λ is the wavelength, h is Planck's constant, c is the speed of light, and E is the energy level of the excited atom.

How do you convert energy level from joules to electron volts?

To convert energy level from joules to electron volts, you can use the conversion factor of 1 eV = 1.602 x 10^-19 J. This means that you would divide the energy level in joules by 1.602 x 10^-19 to get the energy level in electron volts.

What is the value of Planck's constant?

The value of Planck's constant (h) is approximately 6.626 x 10^-34 joule-seconds (J·s).

What is the speed of light?

The speed of light (c) is approximately 299,792,458 meters per second (m/s).

What unit is used for emission wavelength?

Emission wavelength is typically measured in meters (m) or nanometers (nm).
