Solar flares are huge explosions on the Sun that emit lots of electromagnetic radiation.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...
