Double Slit Interference

Objective:
The objective of this lab is to examine the diffraction and limp casts
form by laser glint passing through 2 dicks and verify that the positions of the
maxima in the interference pattern match the positions predicted by theory. [1]

Background:

In quantum mechanics, the double-slit interference experiment is widely performed to dish demonstrate the inseparability of the wave and particle natures of light and other quantum particles. [2] quadruple equalitys will be used in this experiment to right demonstrate this inseparability as well as the slit separation. They argon as follows:

When light passes through two slits, the two light rays emerging from the slits interfere
with each other and produce interference fringes.



The tend to the maxima (bright
fringes) in the interference pattern is given by equation 1 [1]:

par 1 gives: [1]

Where
d represents the slit separation
represents the angle from the centre of the pattern to the mth maximum
m represents the order (0 for the primal maximum, 1 for the first attitude maximum, 2 for the second side maximum, and it continues counting from the centre outwards)
represents the wavelength of light

The following equation is called the small angle approximation formula simply due to the fact that angles wear the ability to be very small we use equation 2. From equation 1 it can be assumed that

Equation 2 gives: [2]

From trigonometry we arrive at the equation,

Equation 3 gives: [3]
Where
y represents the distance on the screen from the centre of the pattern to the...If you want to get a full essay, order it on our website: Orderessay
