=+
Single Opening:
even for a single opening, light waves coming through that opening can undergo
interference
this still creates a pattern of bright and dark spots, but less pronounced
the brightest spot is the central spot with less intense spots on either side,
becoming dimmer with order number
Rayleigh criterion:
the 2 peaks are just barely resolvable as distinct objects if the central maximum of
one of the objects corresponds with the minimum of the other
for a rectangular opening, Rayleigh criterion occurs for:
a
λ
θ

min
where
min
θ
is
the minimum angle of separation (in radians), λ is the wavelength of the light, and
a is the width of the slit opening
a complete circle has 360 degrees, or 2π radians
for a circular opening, Rayleigh criterion occurs for
D

min
θ

the minimum angle of separation (in radians), λ is the wavelength of the light, and

when s is the distance between the two objects, and L is the distance
between the objects and the opening

Modern Physics:
in 1905, Einstein's early work involved studying light
it was discovered that light has wave-particle duality: it can behave as both
we think of electrons as a point particle with a negative charge, however they are
also capable of behaving like a wave
the wavelength of the wave of matter is equal to
p
h
=
λ
, where h is equal to
Planck's constant, 6.63 x 10-34Js and p is equal to momentum (mass times
velocity)
therefore all matter can behave as a wave; however we do not see them

#### Loved by over 2.2 million students

Over 90% improved by at least one letter grade.

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Leah — University of Toronto

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.

Jenna — University of Wisconsin

OneClass has allowed me to catch up with my most difficult course! #lifesaver
