To calculate the energy of a photon of light, you can use the equation:
E = hc/λ
where E represents 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 3.0 x 10^8 m/s), and λ is the wavelength of the light in meters.
Given that the wavelength of the yellow part of visible light is 590 nm (or 590 x 10^-9 m), we can substitute the values into the equation:
E = (6.626 x 10^-34 J*s * 3.0 x 10^8 m/s) / (590 x 10^-9 m)
Simplifying the expression:
E = (1.9878 x 10^-25 J * m) / (590 x 10^-9 m)
E = 3.365 x 10^-19 J
Therefore, the energy of a photon of light with a wavelength of 590 nm is approximately 3.365 x 10^-19 joules (J).
