α- particles, β – particles and γ – rays are all having same energy. Their penetrating power in a given medium in increasing order will be
Options
(a) β, γ, α
(b) γ, α, β
(c) α, β, γ
(d) β, α, γ
Correct Answer:
α, β, γ
Explanation:
Increasing order of penetrating power : α < β < γ For same energy, lighter particle has higher penentrating power.
