Nature of Light and More
Light consists of tiny bundles or packets of energy called this
photons
A mixture of all the colors of light
white
A semicircular arc of colored bands of light formed by refraction in falling raindrops
rainbow
The process in which colors are produced by interference of reflected light
iridescence
This type of wave makes communication possible between ships, airplanes, and cellphones
radio waves
Waves consisting of two transverse waves oscillating at right angles to each other
electromagnetic waves
A triangular glass object that separates light into its component colors through refraction
prism
A mirror with the reflecting surface on the inside of a spherical surface
concave mirror
Each of the dark fringes formed as light interferes destructively from a narrow slit
node
Light waves that have frequencies between microwaves and red visible waves
infrared rays
He first demonstrated the existence of invisible electromagnetic waves
Heinrich Hertz
A three-dimensional image produced by laser light
hologram
When light rays from a distant object pass through heated air, they bend in such a way that the object appears nearby. The image produced is known as this
mirage
A beam of light containing waves that are aligned in the same direction
polarized
The most energetic light waves, capable of penetrating all substances
gamma rays
The use of lasers to transmit signals through narrow glass cables
fiber optics
The three color of pigments that can be combined to make most other colors
subtractive primary colors
The apparent slowdown in time for an object traveling at nearly the speed of light
time dilation
This type of lens curves outward and bends light inward to converge on a point
convex lens
An excited atom releases two photons after a collision
stimulated emission
The phenomenon in which light above a certain frequency knocks electrons loose from the atoms of certain metals
photoelectric effect
The additive primary colors
red green
blue
The idea that gravity is a result of the geometry of space
general theory of relativity
This type of ultraviolet radiation is mostly, but not completely, blocked by the atmospheric ozone layer
AND
The frequency just higher than ultraviolet rays
UVB
x-rays
This is the reason why laser light is extremely intense compared to normal light
The beam is concentrated narrowly and coherently
