Chapter 9, Problem 110P(choose chapter or problem)
The particle nature of light was first proposed by Albert Einstein, who suggested that light could be described as a stream of particles called photons. A photon of wavelength \(\lambda\) has an energy (E) given by the equation: \(E=h c / \lambda\), where E is the energy of the photon in J, h is Planck’s constant \(\left(6.626 \times 10^{-34} J \cdot s\right)\), and c is the speed of light \(\left(3.00 \times 10^{8} \mathrm{~m} / \mathrm{s}\right)\). Calculate the energy of 1 mol of photons with a wavelength of 632 nm.

ANSWER:
Solution 110P
Here, we have to calculate the energy of 1 mol of photons with a wavelength of 632 nm.
We know that
A photon of wavelength λ has an energy (E) given by the equation:
E = hc/λ, -----(1)
where E is the energy of the photon in J, h is Planck's constant and c is the speed of light.
Given that,
Planck's constant h = 6.626 × 10−34
