The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Ultraviolet (UV) "light" is a form of electromagnetic radiaiton. It carries more energy than the normal light we can see.
Visible light is the most familiar part of the electromagnetic spectrum because it is the energy we can see.
Waves of energy are described by their wavelength.
Weather balloons carry instruments high in the atmosphere to measure wind, temperature, and humidity.
