EXAM WITH PRECISE |! |! |!
DETAILED SOLUTIONS |!
wave - Correct answer ✔oscillation that can transport energy from one point
|! |! |! |! |! |! |! |! |! |! |! |!
to another in space
|! |! |!
wavelength (λ) - Correct answer ✔distance between two consecutive peaks or
|! |! |! |! |! |! |! |! |! |! |!
troughs in a wave |! |! |!
the speed of light - Correct answer ✔waves can travel through a vacuum at a
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |!
constant speed of 2.998 ×× |! |! |! |!
|! 10^8 m/s, (denoted by c).
|! |! |! |!
amplitude - Correct answer ✔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 - Correct answer ✔Idealized perfect absorber of all incident
|! |! |! |! |! |! |! |! |! |!
electromagnetic radiation; such bodies emit electromagnetic radiation in
|! |! |! |! |! |! |! |!
characteristic continuous spectra |! |!
continuous spectrum - Correct answer ✔electromagnetic radiation given off in
|! |! |! |! |! |! |! |! |! |!
an unbroken series of wavelengths (e.g., white light from the sun)
|! |! |! |! |! |! |! |! |! |!
electromagnetic radiation - Correct answer ✔energy transmitted by waves that
|! |! |! |! |! |! |! |! |!
have an electric-field component and a magnetic-field component
|! |! |! |! |! |! |! |!
,electromagnetic spectrum - Correct answer ✔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) - Correct answer ✔number of wave cycles (peaks or troughs)
|! |! |! |! |! |! |! |! |! |! |! |!
that pass a specified point in space per unit time
|! |! |! |! |! |! |! |! |!
, hertz (Hz) - Correct answer ✔the unit of frequency, which is the number of
|! |! |! |! |! |! |! |! |! |! |! |! |! |!
cycles per second, s−1
|! |! |!
intensity - Correct answer ✔property of wave-propagated energy related to
|! |! |! |! |! |! |! |! |! |!
the amplitude of the wave, such as brightness of light or loudness of sound
|! |! |! |! |! |! |! |! |! |! |! |! |!
interference pattern - Correct answer ✔pattern typically consisting of
|! |! |! |! |! |! |! |! |!
alternating bright and dark fringes; it results from constructive and destructive
|! |! |! |! |! |! |! |! |! |! |!
interference of waves |! |!
