According to Heel effect:
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.
High intensity x-rays are found at cathode.
Low intensity x-rays are found at anode.
Both of the above.
None.
