L×w×h=v
length times width times height equals volume
the order in which you multiply does not matter

Answer:
D. 4.281 x 10⁻¹⁹ Joules.
Explanation:
- To get the change in energy, we can use the relation:
<em>E = (hc)/λ</em>
where,
E is the energy of the atom.
h is Planck’s constant = 6.626 x 10⁻³⁴ J.s.
c is the speed of light = 2.998 x 10⁸ m/s.
λ is the wavelength of photon = 4.64 x 10⁻⁷ m.
<em>∴ E = (hc)/λ</em> = (6.626 x 10⁻³⁴ J.s)(2.998 x 10⁸ m/s)/(4.64 x 10⁻⁷ m) = <em>4.281 x 10⁻¹⁹ J.</em>
