The wavelength of a photon that has an energy of 5.25 × 10-19 j is m.

The wavelength of a photon that has an energy of 5.25 × 10-19 j is 3.78 × 10-⁷m

HOW TO CALCULATE WAVELENGTH:

E = h × c/λ

Where;

The wavelength of the photon can be calculated as follows:

λ = hc/E

λ = (6.626 × 10-³⁴ × 3 × 10⁸) ÷ 5.25 × 10-¹⁹

λ = 19.878 × 10-²⁶ ÷ 5.25 × 10-¹⁹

λ = 3.78 × 10-⁷m

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
