Answer to Question 1

Answer: Electrons orbit the nucleus of atoms in prescribed zones called shells. Upon receiving energy in the form of a photon, the electron is in an excited state and jumps to its next shell. When the electron returns to its ground state, it releases energy in the form of a photon. The energy emitted by such atoms must occur in discrete packets; at the atomic scale, units of energy are divided into individual parcels.

Answer to Question 2

Answer: Electric wave: the electric component of an electromagnetic wave. magnetic wave: the magnetic component of an electromagnetic wave. wavelength: distance between wave crests. wave amplitude: the height of a wave. wave speed: the speed of light. black body: a hypothetical object that emits the maximum possible radiation at every wavelength. Stefan-Boltzmann law: the intensity of energy radiated by a blackbody increases according to the fourth power of its absolute temperature. Wien's law: hotter objects radiate energy at shorter wavelengths than do cooler bodies. electromagnetic bands: a grouping of wavelength rangesranges.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
