    Answer:

    19.89×10^-26Jm

    Explanation:

    The Energy of a photon is given as;

    E = h×c/λ

    Where h is Plank’s constant.

    c is speed of light

    λ is the wavelength.

    By multiplying both sides of the equation to λ

    E × λ = h×c/λ × λ

    E × λ = h×c

    = 6.63×10^-34× 3×10^8

    = 19.89×10^-26Jm
