Chapter 15-16 test Flashcards
As the wavelength of light waves decreases, frequency in
increases.
The ____ says that the angle of incidence is equal to the angle of reflection
law of reflection
A prism separates white light into colors because the different wavelengths of the different colors causes them to
bend differently
a mirage of water in the road, or a broken straw in a glass of water are caused by what process
refraction
light can be characterized in two ways
wave like and particle like

concave
the lens that can fix farsighted vision is
converging lens
when all subtractive pigment colors are mixed, you get

two or more plane surfaces of a transparent solid at an angle to each other
prism
a lens that bends light waves inwards
convergent lens
the bending of light when crossing mediums

air
if a transverse wave is moving from right to left, the individual particles in the medium are moving..
up and down
waves are often caused by
vibrating objects
the ___of a longitudinal wave radiates outward from its source, while the particles vibrate back and forth about their original positions.
wave front
a wave in which particle motion is perpendicular to wave motion
transverse wave
a term that refers to the high point of a wave
crest
a disturbance at the boundary between two media
surface wave
a wave that requires a medium in which to travel
mechanical wave
a wave in which particle motion is parallel to wave motion
longitudinal wave
a wave that consists of oscillating electromagnetic fields, radiating outward at the speed of light.
electromagnetic wave
a disturbance that carries energy through matter or space
wave
the matter through which a wave travels
medium
waves that need a medium in order to travel
mechanical waves
all waves except electromagnetic are
mechanical
waves that consist of changing electric and magnetic fields in space
electromagnetic waves
electromagnetic waves do not require a _______, they can travel through empty space
medium
types of electromagnetic waves are
