What is the Energy of Light with a Wavelength of 662 nm?

The energy of light with a wavelength of 662 nm can be calculated using the formula:

E = hc/λ

Where:

• E is the energy of the photon
• h is Planck’s constant (6.626 x 10^-34 J·s)
• c is the speed of light (3.00 x 10⁸ m/s)
• λ is the wavelength of the light (662 nm or 662 x 10^-9 m)

Plugging in the values:

E = (6.626 x 10^-34 J·s) * (3.00 x 10⁸ m/s) / (662 x 10^-9 m)

E ≈ 3.00 x 10^-19 J

So, the energy of light with a wavelength of 662 nm is approximately 3.00 x 10^-19 Joules.
