What is the energy (in joules) of the color indigo?

The color indigo has a wavelength of 410.1 nm. What is the energy (in joules) of the color indigo? Answer: E = 4.9 ×10⁻¹⁹ J Explanation: Given data: Wavelength = 410.1 nm or 4.101 ×10⁻⁷ m Energy = ? Solution: Formula: E = hc/λ E = energy h = planck's constant c =speed of light λ = wavelength Now we will put the values in the formula. E = hc/λ E = 6.63 × 10⁻³⁴m² Kg/s . 3× 10⁸ m/s / 4.101 ×10⁻⁷ m E = 19.89 × 10⁻²⁶ m² Kg/s² / 4.101 ×10⁻⁷ m E = 4.9 ×10⁻¹⁹ J
