We begin our discussion of the development of our current atomic model by describing the properties of waves and the various forms of electromagnetic radiation. Dogan Halkman, A.K. Plugging the value of $m$ from here we get an equation with all known constants. Electromagnetic waves travel at the "Speed of Light" at almost 300,000,000 meters per second (to be exact: 299,792,458meters per second) in a vacuum. The wavelength of light is 740 nm (nanometers) or 7.4 10 -7 m (meters). Photons have no mass, but each photon has a specific amount of energy that depends on its frequency (number of vibrations per second). Their part of the spectrum is relatively large compared to the previous categories, ranging from about 0.7 micrometers (700 nanometers) to 1000 micrometers. Wavelengths increase from approximately 10-18 m to 100 km, and this corresponds to frequencies decreasing from 3 1026 Hz to 3 103 Hz. This is the energy that an electron gains when it falls through a potential difference, or voltage, of one volt. X-rays are emitted as the electrons decelerate in the metal. Joshua M. White, Aleese Barron, Matthew R. McCurry, Tim Denham. When a drop of water falls onto a smooth water surface, it generates a set of waves that travel outward in a circular direction. They are also used in Global Positioning Systems (GPS), meteorology, and cooking food. Light in water = 225,000 km/s. Round your answer to 3 significant digits.
