DC.8.5. Conservation of Energy: Broad Concept: Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept, students:
8.5.7. Know the sun's radiation consists of a wide range of wavelengths, mainly visible light and infrared and ultraviolet radiation.
DC.8.8. Waves: Broad Concept: Waves have characteristic properties that are common to all types of wave. As a basis for understanding this concept, students:
8.8.3. Explain how electromagnetic waves differ from mechanical waves in that they do not need a medium for propagation; nevertheless, they can be described by many of the same quantities: amplitude, wavelength, frequency (or period), and wave speed.
