Question

1. What is the energy (in joules) of a single photon of light with a wavelength of 4.80X10-7 meters?

Answer 1

This is a simple question

We will use formula for this question

E= hc/

Where E= energy in Joules

h= planks constant = 6.626×10³⁴ J•S

C= speed of light = 3 ×10⁸ m/S

And = 4.8×10^-7 m

Putting these values in above equation we get

E=( 6.626×10³⁴ × 3× 10⁸) /4.8×10^-7

= 4.14 ×10⁴⁹ J
