Answer:
1.3 × 10⁻²⁸ m
Explanation:
The equation relating the energy (E) and the wavelength (λ) of a wave is
[tex]E =\frac{hc}{\lambda}[/tex]
where h = Planck’s constant and c = the speed of light
[tex]\lambda =\frac{6.626 \times 10^{-34}\text{ J}\cdot \text{s} \times 2.998 \times 10^{8} \text{ m} \cdot \text{s}^{-1}}{1.5 \times 10^{3} \text{ J}} = 1.3 \times 10^{-28}\text{ m}[/tex]
