False. In the spectrum, shorter wavelengths contain more energy than longer ones. This is due to the fact that the energy of a photon is inversely proportional to its wavelength. As the wavelength decreases, the energy of the photon increases. For example, ultraviolet rays have a shorter wavelength and higher energy than visible light.
It is important to understand the relationship between wavelength and energy when considering the effects of different types of electromagnetic radiation on living organisms. For instance, exposure to high-energy radiation such as X-rays and gamma rays can be harmful to human health. On the other hand, low-energy radiation such as radio waves and microwaves are generally considered safe.
