The energy of a photon can be calculated using the equation:
E = hc / λ
Where: E is the energy of the photon, h is Planck's constant (approximately 6.626 x 10^-34 J·s), c is the speed of light in a vacuum (approximately 3.00 x 10^8 m/s), and λ is the wavelength of the photon.
To find the energy of a photon with a wavelength of 1130 nm (nanometers), we need to convert the wavelength to meters:
λ = 1130 nm * (1 m / 10^9 nm) = 1.13 x 10^-6 m
Now we can substitute the values into the equation:
E = (6.626 x 10^-34 J·s * 3.00 x 10^8 m/s) / (1.13 x 10^-6 m)
Calculating the expression:
E ≈ 1.757 x 10^-19 Joules
Therefore, a photon with a wavelength of 1130 nm has an energy of approximately 1.757 x 10^-19 Joules.
