An electromagnetic radiation has an energy of 13.2 keV. Then the radiation belongs to region ofA. visible lightB. ultravioletC. infraredD. X-ray |
|
Answer» Correct Answer - D Given: `E = 13.2 keV` `lambda("in" Å) = (hc)/(E("in"eV)) = (12400)/(13.2 xx 10^(3)) = 0.939 Å ~~ 1Å` X-rays cover wavelengths ranging from about `10^(-8)m (10 nm)` to `10^(-13)m (10^(-4)nm)`. An electromagnetic radiation of energy 13.2 keV belongs to X-ray region of electromagnetic spectrum. |
