Roses Are (Infra)red, (Ultra)violets Are Blue
This Valentine takes an age-old poem and infuses it with new knowledge. Satellites measure light, a form of energy that travels in waves, to produce images. However, one key difference is that satellites can measure light that can’t be seen with the human eye, such as infrared and ultraviolet light. Infrared light has longer wavelengths and lower energy than visible light, while ultraviolet light has shorter wavelengths and higher energy.
