Th6 intensity of radiation from a given source is I. On passing through 36 mm of lead, it is reduced to I / 8. The thickness of lead, which will reduced the intensity to I/ 2will be
detailed solution
Correct option is C
we know that I′=Ie−μx or −μX=logI′/I −μ(36)=log(I/8I) −μx′=log(I/2I) Dividingeq.(1)byeq.(2)363lo8(t 36x′=3log(1/2)log(1/2)=3 x′=363=12mmTalk to our academic expert!
