11BUT SIR I THINK IT IS NOT IN JEE (K absorption edge)
PLEASE CORRECT ME IF I AM WRONG
for a certain metal the K absorption edge is at 0.172 x 10-10m please explain what does this mean also we are given Ka wavelength How to calculate EK i.e. energy of K orbit

62absorption edge A limiting feature in a series of absorption lines from a single element (e.g. hydrogen), representing the wavelength at which the element becomes ionized. In the Balmer series of hydrogen, the lines become closer together as the series limit of 364.6 nm is reached, forming an edge at that wavelength (see Balmer Limit). Similarly, in the Lyman series the lines become closer towards the Lyman limit of 91.2 nm.
I googled it out ;)
