most energy
Each type of electromagnetic radiation has a characteristic range of wavelengths. The longer the wavelength or the more stretched out it appears , the less energy is carried. Short, tight waves carry the most energy. This may seem illogical, but think of it in terms of a piece of moving rope. It takes little effort by a person to move a rope in long, wide waves. To make a rope move in short, tight waves, a person would need to apply significantly more energy. The sun emits Figure 5.10 a broad range of electromagnetic radiation, including X-rays and ultraviolet UV rays. The higher-energy waves are dangerous to living things; for example, X-rays and UV rays can be harmful to humans.
