Question

Identify the two types of radiation shown in the figure below. Explain your reasoning.

Answer 1

Answer:- $\gamma$ and $\alpha$ radiation.

Explanations:-  Alpha particle is helium nucleus with two protons and two neutrons and so it has +2 charge where as gamma is a form of light, so these are rays and not particles. Since these are rays, the charges for gamma rays is zero means they are neutral.

When alpha particles are passed through electromagnetic field they are repelled by the positive plate and attracted by the negative plate as there is an attraction between opposite charges. So, the line we see towards positive plat is representing an alpha particle radiation.

Since gamma rays are neutral, they are not deflected in electromagnetic field and go straight. So, the other line in the diagram is representing gamma rays radiation.

Answer 2

There are two types of radiations in the image above, one which is deviated towards the negative pole and another which is passing without any deviation. The one which is deviated towards the negative field is Alpha radiation and the one which is not deviated by any pole is known as Gamma radiation.

In Alpha radiation, we get an alpha particle which has +2 charge and therefore it is attracted towards negative pole.

$_{Z}^{A}\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_{2}^{4}\textrm{He}$

Charge on He molecule is +2 and it is also known as alpha particle.

In Gamma-radiations, a gamma particle is released which does not carry any charge therefore it is not deviated by any of the pole.$_{Z}^{A}\textrm{X}\rightarrow _{Z}^{A}\textrm{X}+_{0}^{0}\gamma$
