The three main types of radioactive decay are:
- Alpha, beta, delta
- Alpha, beta, gamma
- Beta, gamma, delta
Correct Answer

A. Alpha, beta, gamma

Explanation

The correct answer is alpha, beta, gamma. Alpha decay occurs when an unstable nucleus emits an alpha particle, consisting of two protons and two neutrons. Beta decay involves the emission of a beta particle, which can be either an electron or a positron. Gamma decay, on the other hand, involves the release of gamma rays, which are high-energy photons. These three types of radioactive decay are the most common and well-known mechanisms by which unstable atoms undergo nuclear transformations.

Gamma rays have the lowest frequency in the EM spectrum.
- True
- False
Correct Answer

A. False

Explanation

Gamma rays actually have the highest frequency in the electromagnetic (EM) spectrum, not the lowest. The EM spectrum is a range of different types of electromagnetic radiation, ordered by their frequencies. Gamma rays have the shortest wavelengths and highest frequencies, while radio waves have the longest wavelengths and lowest frequencies. Therefore, the statement that gamma rays have the lowest frequency is incorrect.
