Final answer:
Gamma rays have a very small wavelength, with high frequencies and high energy, allowing them to penetrate matter effectively.
Step-by-step explanation:
Gamma rays have a very small wavelength. Due to their high frequencies, gamma rays have shorter wavelengths than visible light, and their high frequency corresponds with high energy as indicated by their position on the electromagnetic spectrum. Gamma rays are known for their ability to penetrate matter due to this high energy, which is much greater than that of X-rays or visible light.
Gamma rays have a very small wavelength. Gamma rays are a type of electromagnetic radiation that have the shortest wavelength and highest frequency among all types of electromagnetic waves.
