Calculate Energy 488.0 Nm Wavelength of Argon Laser

Introduction

Argon lasers are widely used in scientific research, medical procedures, and industrial applications due to their precise wavelength output. The 488.0 nm wavelength is particularly significant because it falls within the visible light spectrum, making it useful for applications like fluorescence microscopy and laser surgery.

The energy of photons emitted by a laser can be calculated using Planck's equation, which shows the relationship between photon energy and wavelength. Understanding this energy is crucial for determining the laser's effectiveness and safety in various applications.

Formula

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

For the 488.0 nm wavelength, we first convert the wavelength from nanometers to meters:

Example Calculation

Let's calculate the energy of a photon with a wavelength of 488.0 nm:

1. Convert the wavelength to meters: 488.0 nm = 4.880 × 10^-7 m
2. Plug the values into Planck's equation:

   E = (6.62607015 × 10^-34 J·s) × (299,792,458 m/s) / (4.880 × 10^-7 m)

3. Calculate the energy:

   E ≈ 4.09 × 10^-19 J

4. Convert the energy to electron volts (eV):

   1 eV = 1.602176634 × 10^-19 J

   E ≈ 4.09 × 10^-19 J / 1.602176634 × 10^-19 J ≈ 2.55 eV

The energy of a photon with a wavelength of 488.0 nm is approximately 2.55 electron volts.
