to infinity and beyond
can you see infrared light?
no p 344/5
this theory states that light is composed of individual light particles that are too small to see
particle theory of light
this says the angle of reflection equals the angle of incidence
law of reflection 354
these rays are deadly and used to kill cancer cells
gamma rays p 350
these types of materials are those that you can clearly see through because they allow most of the light that strikes them to pass through
transparent p 351
t/f the speed of light is dependent on temperature
false, p 338
this scientist said light was not in particles but in waves, called the wave theory of light
Christian Huygens p339
when light refracts into a substance that it must slow down the light will bend in a perpendicular line in which way?
toward the surface it strikes p356
these rays pass through sking and other soft tissues but not enough energy to pass through dense structures
this material allows light to pass but scatters the light waves as they pass
transluscent p351
What does affect the speed of light?
the medium in which it travels, p 338
what does the theory of wave particle duality say?
that the spectrum of light could be both a wave and a particle
does refraction always occur when light enters a medium
no p358
this light has enough energy to kill living tissue
UV light p349
these materials absorb or reflect all the light that strikes them
t/f light travels the fastest through gases
true p338
t/f the theory of speical relativity states that the speed of light is the ultimate speed limit because no object with mass can travel faster than light
t p338
these are light waves that only vibrate in one plane
polarized light p358
these light waves have lower frequencies and longer wavelengths than red light in the visible range
infrared p345
we call the little packets of energy from light this in today's terms
photons p 343
does light need a medium to travel through?
no
this is the currently accepted theory of light
quantum mechanical theory of light p 343
this happens when light rays from the sun pass through the tiny particles and molecules in Earth's atmosphere, and the particles redirect light waves
scattering p 360
a transverse wave composed of oscillating electric and magnetic fields that are perpendicular to each other and to the direction the wave travels
electromagnetic wave p336
what do fiber optic cables transport?
light p358
