They don’t carry much energy and are therefore considered safe by most people. When light crosses a boundary into a medium with a high refractive index (eg. Waves with lower frequencies have longer wavelengths! The analysis of the wave can be based upon comparison of the local wavelength with the local water depth. While all light across the electromagnetic spectrum is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.. For example, different detectors are sensitive to different wavelengths of … Lower frequency = longer wavelengths or shorter wavelengths?
