What is the energy of a mole of photons that have a wavelength of 745 nm? (h = 6.626 × 10⁻³⁴ J • s and c = 3.00 × 10⁸ m/s) What is the wavelength of a photon if the energy is 7.03 × 10⁻¹⁹ J? (h = 6.626 × 10⁻³⁴ J • s)

The energy carried by a single photon of 535 nm light is 3.71 × 10−19 J.

The equation used to find the energy in a mole of photons is E= hc/lambda where h is Planck's constant, c is the speed of light and is the wavelength of light.

Option B is correct.

Step-by-step explanation:

Diagram of given scenario shown below.

Given that,

Diameter of cylinder is .

Height of cylinder is .

So, Radius of cylinder is

Volume of cylinder =                    {where, , is the radius                                                  

                                                               of cylinder and is height of cylinder}

Substituting the values we get,

Volume of cylinder

Therefore, Required volume of Cylinder rounding it to the nearest tenth ≈ .

Hence, option B is correct.
