Question

Which of the following statements is true of a beta Particle?

(A) Its speed in a vacuum is 3 x 10⁸ m/s.

(B) It has a charge equal and opposite to that of an alpha particle.

(C) It is more penetrating than a gamma ray of the same energy.

(D) It has a mass of about 1,840 times that of a proton.

(E) It can exhibit wave properties.

Answer 1

The correct option is: (E) It can exhibit wave properties.

Explanation:

A beta particle, like all matter, can exhibit wave properties. Since the particle is so small, it can more readily show these wave properties than normal size matter.
