State the speed of each of α, β and γ radiations.

Class 10 | ICSE | Physics | Radioactivity | Selina

State the speed of each of α, β and γ radiations.

Solution:

The gamma rays have speed equal to light. Because of their mass difference, beta rays have a lower velocity than gamma rays and a higher velocity than alpha rays.

The speed of α radiations is of the order of 10⁷ m s^-1,

Speed of β radiations is of the order of 10⁸ m s^-1 and

The speed of γ radiations is same as the speed of light i.e., 3 × 10⁸ m s^-1
