Final answer:
In the electromagnetic spectrum, there is an inverse relationship between energy level and wavelength.
Step-by-step explanation:
In the electromagnetic spectrum, there is an inverse relationship between energy level and wavelength. As the wavelength decreases, the energy level increases. This means that shorter wavelengths, such as gamma rays and X-rays, have higher energy levels, while longer wavelengths like radio waves have lower energy levels.
For example, gamma rays have the shortest wavelength and the highest energy level in the electromagnetic spectrum. They are often used in medical imaging and cancer treatment because of their ability to penetrate tissues. On the other hand, radio waves have the longest wavelength and the lowest energy level. They are used for communication purposes, such as transmitting radio and television signals.
