Gamma rays are

• A. high-energy photons with the same mass and charge as an electron.
• B. high-energy photons with no mass or charge.
• C. high-energy photons with no mass, but the same charge as an electron.
• D. low-energy photons with the same mass and charge as an electron.
• E. low-energy photons with no mass or charge.

Answer: (B)

Verified step by step guidance

1. Understand the nature of gamma rays: Gamma rays are a form of electromagnetic radiation, similar to X-rays but with higher energy.
2. Recall the properties of photons: Photons are elementary particles that are the quantum of light and all other forms of electromagnetic radiation. They have no mass and no electric charge.
3. Differentiate between high-energy and low-energy photons: Gamma rays are characterized by their high energy compared to other types of electromagnetic radiation like visible light or radio waves.
4. Clarify the misconception about mass and charge: Unlike electrons, which have mass and charge, photons (including gamma rays) do not possess mass or charge.
5. Conclude with the correct description: Gamma rays are high-energy photons with no mass or charge, distinguishing them from particles like electrons.
