Answer:

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

When copper is bombarded with high-energy electrons, X rays, with a wavelength of 0.154 nm (λ) are emitted.

We can calculate the energy (E) associated with the photons of these X rays using the Planck-Einstein relation.

E = \frac{h \times c }{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times 10^{8}m/s ) }{0.154 \times 10^{-9} m } ]= 1.29 \times 10^{-15} JE=
