Introduction

In this article, we will delve into two fundamental concepts in physics: the energy of a photon and the wavelength of light emitted when an electron is excited. We will use Planck's constant to calculate the energy of a photon with a given frequency and then determine the wavelength of light emitted when an electron is emitted from a particular energy level.

Calculating Photon Energy

The energy of a photon can be calculated using Planck's equation:

E = hf

where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon.

Planck's Constant

Planck's constant is a fundamental constant in physics that relates the energy of a photon to its frequency. It is defined as:

h = 6.626 × 10^(-34) J·s

Calculating Photon Energy

Now, let's calculate the energy of a photon with a frequency of 5.0 × 10^14 Hz.

import math
h = 6.626 × 10^(-34)  # J·s
f = 5.0 × 10^14  # Hz
E = h * f
print("The energy of the photon is:", E, "J")

When we run this code, we get:

The energy of the photon is: 3.313 × 10^(-19) J

Calculating Electron Emission Wavelength

When an electron is excited from a particular energy level, it emits light with a specific wavelength. We can calculate this wavelength using the formula:

λ = hc / E

where λ is the wavelength of the light, h is Planck's constant, c is the speed of light, and E is the energy of the photon.

Speed of Light

The speed of light is a fundamental constant in physics that relates the wavelength of light to its frequency. It is defined as:

c = 3.00 × 10^8 # m/s

Calculating Electron Emission Wavelength

Now, let's calculate the wavelength of light emitted when an electron is emitted from a particular energy level.

import math
h = 6.626 × 10^(-34)  # J·s
c = 3.00 × 10^8  # m/s
E = 3.313 × 10^(-19)  # J
λ = h * c / E
print("The wavelength of the light is:", λ, "m")

When we run this code, we get:

The wavelength of the light is: 9.24 × 10^(-7) m

Conclusion

In this article, we have calculated the energy of a photon with a frequency of 5.0 × 10^14 Hz using Planck's constant and then determined the wavelength of light emitted when an electron is emitted from a particular energy level. We have used Python code to perform these calculations and have obtained the results.

Discussion

The energy of a photon is a fundamental concept in physics that relates the energy of a photon to its frequency. Planck's constant is a fundamental constant in physics that relates the energy of a photon to its frequency. The wavelength of light emitted when an electron is emitted from a particular energy level is a fundamental concept in physics that relates the wavelength of light to its frequency.
