Chapter 8 Review Flashcards
what was the name of the book in which newton published his theory of light
opticks
which theory of light did newton propose
particle theory
name the scientists that proposed the wave theory of light
Heightens and Sr Thomas Young
how does a electro and magnetic waves travel with respect to each other
right angles/perpendicular
individual who demonstrated the existence of invisible electromagnetic waves primarily through radio waves
Heinrich hertz
what effect occurs when you have light having the ability to knock and electro out of a metal
photoeletric effect
new name for a bundle of energy referred to as light
photon
what do we call the portion of the electromagnetic spectrum to which our eye responds
visible light/visible spectrum
what part of the electromagnetic spectrum is considered to be light
all of it
if all colors of light are mixed together, what color is produced
white
3 primary additive colors
red green blue
3 subtractive primary colors
magenta cyan yellow
when red green and blue are mixed together, what color is made
white
what happens if you mix magenta, yellow, and cyan pigment together
black
what color of light is produced if we take and additive primary along with its compliment
white
yes or no : is light a wave
yes
does light behave and obey the law of reflection
yes
what type of image is always produced by a convex mirror
virtual
what type of mirror has a reflecting side on the inside of the spherical surface
concave
why am I able to see objects around me
reflection
why is it then if I see objects b/c light is reflected back to my eyes, why can I not see myself when looking at other objects
it doesn’t reflect parallel back to you
piece of glass/other substance specifically designed to refract light
lens
what type of lens causes light to bend to a singular point
convex
what occurs when light waves from a distance object are refracted by heated air so the object appears to be nearby
mirage
what phenomenon occurs when we see stars twinkle in the night sky
scintillation
what occurs due to rain in front of us and the sun behind us
rainbow
what occurs when we have the interference of light on the curved surface of an object
iridescence
when we diffract light (especially through the diffraction grating process) the see alternating fringes of light that are bright fringes and dark fringes, what do we call the bright fringes
antinodes (dark regions - nodes)
scientific technique that analyzes a substance or phenomenon by observing a light spectrum
spectroscopy
when we observe light traveling, it is either red or blue shifted. why does that occur?
the doppler effect
what occurs when light has been oriented in one axis?
polarized
name one of the divisions of the electromagnetic spectrum
radio waves, x-rays, gamma ray, microwaves, infrared rays, ultraviolet radiation, visible light
division of the electromagnetic spectrum with the highest frequency
gamma rays
division of the electromagnetic spectrum that cooks materials
microwaves
division of the electromagnetic spectrum responsible for radar
microwaves
of the 3 types of ultraviolet radiation, which of the 3 is primarily responsible for sunburn
UVB
which branch of the elctromagnetic spectrum is responsible for medical imaging
x rays
the physicist that showed that the energy of the wave is tied to its frequency
Max Planck
what is light amplification by stimulated emission of radiation
LASER
what has occurred when an atom emits 2 photons
stimulated emission
if we have a singular frequency of light
monochromatic light
the speed of light is constant in a vaccum
yes
what theory of relativity deals with changes that occur when you travel the speed of light
special
what occurs to time if you increase gravity
time dilation
if I am traveling at 99% the speed of light, what will happen to the length of the object?
it contracts (gets shorter)
when waves have the same frequency as each other
in phase
spreading of waves as they pas through a narrow gap
diffraction
