Here,
energy of a quantum = 1.68 keV
for the wavelength
energy of a photon = h* c/wavelength
1.68 *10^3 * 1.602 *10^-19 = 6.626 *10^-34 * 2.9972 *10^8/wavelength
wavelength = 7.3789634* 10^-10 m
the wavelength is 7.3789634* 10^-10 m

To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given the symbol...
