According to Heel effect:: (A) High intensity x-rays are found at cathode., (B) Low intensity x-rays are found at anode., (C) Both of the above., (D) None.
Answer is C. According to “Heel effect”, when cathode rays strike anode target, X-rays with high intensity are found towards cathode side of central ray and X-rays with low intensity are found towards anode. This is due to self absorption of photons in the anode target.
