The Wave Nature of Light
Measure of the bending of a ray of light when passing from one medium into another
Index(es) of Refraction
Are variables in
Snell's Law
Is the formula used to
Describe the relationship between the angles of incidence and refraction, when referring to waves passing through a boundary between two different mediums.
Light Waves
This occurs when two or more waves have the same frequency and are coherent
Interference
A pattern of alternating nodal and anti-nodal lines
Interference Pattern
When a dark spot is produced
Destructive Interference
The dark spot produced is called a
Minima
When a bright spot is produced
Constructive Interference
The bright spot produced is called a
Maxima
2 more items...
The difference in distance traveled by the two waves from their respective sources to a given point on the pattern
Path Length Difference
Is equivalent to order maximum times
Determines the type of (constructive or destructive)
When interference occurs after waves from a single source travel through 2 slits before displaying an interference pattern on a screen.
Double Slit Interference
When interference occurs after waves from a single source travel through a single slit before displaying an interference pattern on a screen.
Single Slit Interference
When light goes through the single narrow slit, it spreads out to form a
Single Slit Diffraction
The wavelets going forward all travel the same distance to the screen and interfere constructively to produce the
Formula locates
When interference occurs after waves from a single source travel through 3 or more slits before displaying an interference pattern on a screen.
Diffraction Grating (Multiple Slit Interference)
When light waves reflected by the upper and lower boundaries of a thin film interfere with one another
Thin Film Interference
The type of interference (constructive or destructive) is dependent on the
Phase Shift
The existence of the phase shift is dependent on the values of the mediums'
Strength is measured in
Intensity
Which is exponentially proportional to
Energy
Light waves in which the vibrations occur in a single plane
Polarized Light (Polarization)
Happens when light travels through
Polarizers
After passing through a second polarizer, the intensity is dependent on
The Law of Malus
The intensity is reduced based on the magnitude of the angle of the
The angle at which an incident beam of unpolarized light is reflected after complete polarization
Brewster's Angle
Dependent on the two mediums'
Light waves in which the vibrations accelerate in
random directions
Unpolarized
Distance between corresponding points of two consecutive waves
Wavelength
Huygens' Principle
His principle stated that
Each point on the wave front is a new source of a spherical wavelet that spreads out spherically at wave speed.
Can be visualized using
Huygens’ Wave Model
Is applied in
Air Wedges
If created between two uniform pieces of glass and illuminated, it will result in an
