Question

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

Answer 1

E = 4.9 ×10⁻¹⁹ J

Step-by-step 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
