Short-wavelength refers to electromagnetic waves that have a shorter distance between their peaks compared to longer wavelengths. These waves are typically found at the higher energy end of the electromagnetic spectrum, including types like ultraviolet light, X-rays, and gamma rays. Short wavelengths are associated with higher frequencies, which means they can carry more energy. In practical terms, short-wavelength radiation can have various applications and effects. For example, X-rays are used in medical imaging to view the inside of the body, while ultraviolet light can cause sunburns. Understanding short wavelengths is essential in fields like physics, medicine, and communications.
