The color indigo has a wavelength of 410.1 nm. what is the energy (in joules) of the color indigo?

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 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

Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules.
