Chapter 8 & 10 Flashcards
The type of EM radiation that has frequency just a bit shorter than that of visible light is
infrared
Which of the following is not a common use of microwaves?
medical imaging.
EM waves in a vacuum travel at a speed
(A) of c.
(B) that varies with their wavelength.
(C) that varies with their intensity.
(D) of 3 * 108 m/s.
A and D
a quantum of electromagnetic radiation
photon
radar utilizes this
microwaves
one way for an excited atom to lose energy
photon emission
in the Bohr model of the atom this is quantized
electron energy
tells us that particles can’t be precisely localized
Heisenberg uncertainty principle
the lowest energy level in an atom
ground state
causes an electron to make a transition to a higher energy level
photon absorption
works with AC but not DC
transformer
causes skin to tan
ultraviolet rays
the highest frequency electromagnetic waves
gamma rays
The type of EM radiation emitted when high speed electrons decelerate as they are smashed into a metal target is
x ray.
The EM wave that has the highest frequency in this list is
gamma rays.
What does “IR” stand for?
infrared
The lowest frequency visible light is
red
