Document Summary
Chapter 5: electrons in atoms: electromagnetic radiation a form of energy that exhibits wavelike behavior as it travels through space, forms of electromagnetic radiation include, x-rays, gamma rays, radio waves, microwaves. Light as a particle: waves of light are made up of photons, photons have no mass and are particles that can travel at the speed of light, wave-particle duality has the properties of waves & particles. 1: the electromagnetic spectrum also includes all the other forms of electromagnetic radiation. White light consists of all visible wavelengths mixed together: a prism can be used to separate these colors because shorter wavelengths refract more in water, glass, and in plastic. The electromagnetic radiation spectrum: elf extremely low frequency radio (used in the navy to communicate with submarines underwater clear nonstatic communication, radio/tv waves general communication, microwaves cooking. Infrared heat lamps: ultraviolet causes sunburns, x-ray used for internal body pictures, gamma rays highest energy electromagnetic radiation.
