Energy is transferred by the photon of light in the space. The photons are the energy particles and can transfer energy in the absence of any medium. This energy is known as the photon energy and the energy is carried by the electromagnetic waves.

Photon energy is the type of energy carried by a photon. The electromagnetic frequency of the photon determines the energy level. hence it is photon energy is directly proportional to the frequency of the photon and inversely proportional to the wavelength of the photon.

The wavelength calculator is an online tool to find photon energy. You need to describe the relative frequency and the wavelength of the photons to find the relative energy level of the photons.

**How to Measure the Energy of a Photon?**

The energy of the photon can be described by the given formula:

**E = hf**

Where:

E = photon energy level

h = Planck’s constant

f = The frequency of the photons measured in the Hertz or Hz

The above-mentioned formula is only used to describe the energy level of a photon. When more photons are emitted, then we add the “n” in the formula:

**E = n × h × f**

Where “n” represents the number of photons. We measure the energy of the photons in the Joules and electronvolt (eV).

You need to remember

**1 Joule = 6.24 × 1018 eV**

The radiations as gamma rays in large units to represent the photon energy. The wavelength calculator provides a simple transfer of energy in space.

**Formula of the Photon Energy:**

The speed of light is constant in space and we represent it by the formula “c”. You need to understand that high frequencies like gamma rays and X-rays travel at the same speed as low-frequency photons like infrared radiation.

The speed of the light remains constant as when the frequency of the photons increases the wavelength of the photons decreases and vice versa. The wavelength calculator can determine the energy of the photons but you need to mention the relative frequency and the wavelength of the photons.

Now the speed of light is:

**c = λf**

You need to understand the wavelength and the frequency are interdependent parameters, so the equation for the energy for photons is represented by the formula:

**E = hf or E = hc/λ**

Where,

- E = energy of the photon
- h = Planck’s constant (6.62607015) × 10-34 J.s or kg m2 s−1)
- f = photon frequency
- λ = photon wavelength
- c = speed of light (3 x 108 meters/second)

The photon energy at 1 Hz = 6.626 × 10−34 J and Planck’s constant in terms of the eV= 4.14 × 10−15 eV· s.Estimate the photon energy of the rays with the online wavelength calculator.

**Application of Photon Energy Medicines:**

Photon energy has a wide variety of applications in the field of medicine. The treatment of the cancer cells as the infrared and ultraviolet rays are readily absorbed by the biological tissues. The online wave length calculator is a simple way to determine the wavelength and frequency of the photon rays. This is the main reason photon energy is used in the treatment and diagnosis of a disease.

The common applications of photon energy in the field of medicine are:

- Tissue incision or cutting
- Vaporigng a specific tissue region
- To seal wounds without human intervention
- Surgery of cancer cell

The photon energy offers a wide variety of solutions in the medication especially treating and removing the cancer cells in the body. Various rays have different energy levels just use the wavelength calculator.

**Conclusion:**

The photons are the energy particles and are used to transfer energy from one medium to another. Photon energy is commonly used in the treatment of cancer cells. The infrared and ultraviolet rays are readily absorbed by the biological tissues. These are high-energy particles and are used to remove the tumor cells or cancer cells from the body.
