These waves have electric and magnetic properties - electromagnetic waves. Wave characteristics - horizontal distance between two successive crests is the wavelength. We will discuss this method more later in the course. Evaporation cools the environment. As molecules leave, faster ones leave first, average speed decreases and so the temperature of the object cools.
Latent heat is responsible for keeping a cold drink with ice colder than one without ice.
As ice melts its temperature doesn't change, added heat breaks down the rigid crystal pattern. Phase changing is important for transferring energy in the atmosphere. For example, Evaporation over tropical waters, the water vapor can move poleward and condense. Eyes are sensitive to radiation between 0.4 and 0.7 microns. All things no matter how small emit radiation.
