The spacing is 14.4 nm (nanometers).
It is 14.4 * 10^(-9) m
And 1 mm = 1 * 10^(-3) m
14.4 nm * 105 = 1,512 nm = 1.512 micrometers = 0.001512 mm
Or : 1.512 * 10^(-3) mm
Answer: The total width of crystal is 0.001512 mm.

Calculate the change in energy of an atom that emits a photon of wavelength 2.21 meters. (Planck’s constant is 6.626 x 10-34 jou

laila [671]

The Energy of an atom that emits a photon of wavelength 2.21 m is 3.028 × 10⁻¹⁹ J.
I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light, ν = frequency, λ= wavelength, h = Planck's Constant
