Question

state any three characteristic properties of beta rays

Answer 1

   1)Beta particles are energetic electrons, they are relatively light and carry a single negative charge.

2)Their mass is equal to the mass of the orbital electrons with which they are interacting and unlike the alpha particle a much larger fraction of its kinetic energy can be lost in a single interaction.

3)Since they have very low mass, beta particles reach mostly relativistic energies.

Answer 2

1 Beta rays get aataracted towards positively charged plate

2 there ionization power is low

3 there penetration power is 100 times that of alpha rays

4 there fluorescence power is very low
