Question

An X-ray generator produces photons with energy 49 600 eV orless. Which one of the following phrases most accurately describesthe wavelength of these photons?

a. 0.75 nm or longer
b. 0.75 nm or shorter
c. 0.025 nm or longer
d. 0.25 nm or shorter
e. 0.050 nm or longer An X-ray generator produces photons with energy 49 600 eV orless. Which one of the following phrases most accurately describesthe wavelength of these photons? 0.75 nm or longer 0.75 nm or shorter 0.025 nm or longer 0.25 nm or shorter 0.050 nm or longer

Explanation / Answer

Energy E = 49600 eV              = 49600 * 1.6 * 10 ^ -19 J wavelength of the photon = hc / E where h = planck's constant = 6.625 * 10 ^ -34 J s            c= speed of light = 3 * 10 ^ 8 m / s substitue values weget = 2.5044 *10 ^ -11 m                                      = 0.025 nm So, option ( c ) is correct
