A radioactive source emits three types of radiations.

(a) Name the three radiations.

(b) Name the radiations which are deflected by the electric field.

(c) Name the radiation which is most penetrating.

(d) Name the radiation which travels with the speed of light.

(e) Name the radiation which has the highest ionizing power.

(f) Name the radiation consisting of the same kind of particles as the cathode rays.

Solution:

a) The three forms of radiation are alpha, beta, and gamma.

(b) The alpha and beta radiations are the ones that are deflected by the electric field.

(c) The most penetrating radiations are gamma rays.

(d) Gamma radiation travels faster than light.

(e) The ionisation power of alpha radiation is the highest.

(f) Beta radiations are those that contain the same type of particles as cathode rays.
