What wavelength of radiation has photons of energy 2.87×x10−18 j?

The wavelength of radiation that has a photon of energy of 2.87 × 10-¹⁸J is 7.2 × 10-⁸nm

HOW TO CALCULATE WAVELENGTH:

E = hc/λ

Where;

λ = (6.626 × 10-³⁴ × 3 × 10⁸) ÷ 2.87 × 10-¹⁸

λ = 19.88 × 10-²⁶ ÷ 2.78 × 10-¹⁸

λ = 7.2 × 10-²⁶+¹⁸

λ = 7.2 × 10-⁸nm

explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
