FINAL EXAM CHM 151 RIO SOLADO M.SCHAAB ACTUAL UPDATED QUESTIONS
AND CORRECT ANSWERS
wave oscillation that can transport energy from one point to another in space
wavelength (λ) distance between two consecutive peaks or troughs in a wave
the speed of light waves can travel through a vacuum at a constant speed of 2.998 ××
10^8 m/s, (denoted by c).
, amplitude extent of the displacement caused by a wave (for sinusoidal waves, it is one-half
the difference from the peak height to the trough depth, and the intensity is
proportional to the square)
blackbody Idealized perfect absorber of all incident electromagnetic radiation; such bodies
emit electromagnetic radiation in characteristic continuous spectra
continuous spectrum electromagnetic radiation given off in an unbroken series of wavelengths (e.g.,
white light from the sun)
electromagnetic radiation energy transmitted by waves that have an electric-field component and a
magnetic-field component
electromagnetic spectrum range of energies that electromagnetic radiation can comprise, including radio,
microwaves, infrared, visible, ultraviolet, X-rays, and gamma rays; can be specified
in wavelengths and frequencies
frequency (ν) number of wave cycles (peaks or troughs) that pass a specified point in space per
unit time
hertz (Hz) the unit of frequency, which is the number of cycles per second, s−1
intensity property of wave-propagated energy related to the amplitude of the wave, such
as brightness of light or loudness of sound
