Light exam Flashcards
polarization an interference traveling as a wave
light waves can be blocks( polarized) and create interference patterns(nodes) just like sound waves and physical waves like an old reflected
polarized
blocks light and light travels in different patterns
interference
waves collide and create nodes
relationship between frequency and wavelength
if you increase frequency of the wavelengths shortens and decreases
wave
transfer of energy
amplitude
height of the wave
Nodes
Area of destruction interference, formed from crest and trust meeting
pulse wave
Single chunk of energy
periodic wave
A continuous flow of energy
physical waves
require a medium
electromagnetic waves
travel at the same speed no medium
destructive interference
when I crossed and a truck meet the Waze cancel out and create notes
constructive interference
went to cross and two trucks meet the wave gets bigger
three types of Spectra
continuous, omission, absorption
where can continue as a mission and absorption waves be found
Incandescent , black, son
continuous spectrum
Color gradually changes from one color to the next
emission spectrum
brightly colored lines on a black background
absorption spectrum
Black lines on a colorful background
how do we determine how old a star is
absorb energy quickly, releases it slowly, can globe without a uv
why do we call it blacklight
because it meant to type of light that we can see, Violet
difference between florescence and phosphorescence
phosphorescence glows in the dark
relationship between notes, frequency and wavelength
blue- more notes, high frequency, short wavelength
red- West notes, low-frequency, less wavelength
units for speed of light, frequency, wavelength, energy
light- C, m/s
frequency- V, 1/sec
wavelength- m, å, nm
energy- E, calories
how was light produced
The Adam observes energy, the electron moves to a higher energy level, the electron falls back toward the nucleus, the photon is released
wavelength to nano meters
hundreds
Energy of wave
subtract, -20ish
finding frequency
energy change/ 1.58x10-34, 14
finding wavelength
3x10^8/ frequency, -6ish
what was the relationship that was between the distance the electron fell on the frequency of light
The further falls the more energy is a emitted the higher the energy the higher the frequency
x-rays, infrared, Roy G. Biv, radio, gamma, ultraviolet
gamma, x-ray, UV, rainbow, infrared, radio
