Answer:
Gamma rays cannot be seen or felt, but can cause ionization.
Step-by-step explanation:
Gamma rays are a type of electromagnetic radiation, similar to X-rays, radio waves, and visible light. They have the highest energy and the shortest wavelength in the electromagnetic spectrum. Gamma rays are emitted by the nuclei of atoms during certain types of radioactive decay.
Gamma rays cannot be seen or felt because they are electromagnetic waves, and not particles like visible light or sound waves. Gamma rays do not have enough energy to excite the atoms in our eyes, so we cannot see them. They also do not have enough energy to cause vibrations in our ears, so we cannot hear them.
Gamma rays can cause ionization when they interact with matter, meaning that they can knock electrons off atoms and molecules, creating ions. When gamma rays pass through matter, they can disrupt the electrons in atoms and molecules, which can cause damage to living cells and genetic material. This is why gamma rays are considered to be dangerous and are used in very limited circumstances, such as in cancer treatment, where the goal is to destroy cancer cells.
