What is the wavelength of a 83 keV photon?

In summary, the wavelength of a 83 keV photon is 4.99 E-20 meters. It is important to convert to eVs to make the units work out, specifically using the version of Planck's constant expressed in eV*s. This can be done by multiplying the constant by 4.14E-15evsec/83000eV.

What is the wavelength of a 83 keV photon?

does it matter whether or not you convert to eVs? or can it remain keV?

i have it as 83000eVs=6.6E-34*3E8/lambda

Think about it. What is one of the things that the proportionality constant (Planck's constant in this case) does? Make the units work out. So it has to be the version of Planck's constant that is expressed in the right units to do so, not J*s in this case, but eV*s. Well, if it isn't, then convert it.

Edit: Oh, that wasn't your question, but from the looks of it, it's a good thing I brought it up. Take a look at the constant you are using.

1. What exactly is a photon?

A photon is a fundamental particle that carries electromagnetic energy. It is the basic unit of light and other forms of electromagnetic radiation.

2. How is the wavelength of a photon measured?

The wavelength of a photon is measured by determining the distance between two consecutive peaks or troughs of its electromagnetic wave. This distance is usually expressed in units of meters (m) or nanometers (nm).

3. What does 83 keV refer to in the context of a photon's wavelength?

The term "83 keV" refers to the energy of a photon, specifically its kinetic energy. It is a unit of measurement used to describe the amount of energy carried by a photon.

4. How does the energy of a photon relate to its wavelength?

The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. This means that as the energy of a photon increases, its wavelength decreases, and vice versa.

5. Why is the wavelength of a photon important to know?

The wavelength of a photon is important to know because it helps us understand the properties and behaviors of electromagnetic radiation. It also plays a crucial role in various scientific fields, such as optics, astronomy, and quantum mechanics.
