Answer:
d y / x = m λ
Explanation:
<em>When a laser beam, which is light coherent, hits the slits, part of each beam passes through each slit.</em>
<em>When this is noticed on a screen that is quite far from the slits, a series of intense linear moved apart by dark areas. </em>
<em>The explanation for this distribution of the light pattern is that when adding the rays that come out of the slits they travel different distances, which makes a difference in optical path and if this difference is an integer multiple of the wavelength </em>
<em>a bright line is defined as</em>
<em />
<em> d sin θ = m λ </em>
<em />
<em> d is the distance between the slits (0.1 mm)</em>
<em> since the angle of the measurements is small, the tangent approximated will be</em>
<em> tan θ = y / x = sin θ /sin θ</em>
<em> </em>
<em> sint θ = y / x</em>
<em />
<em>Substituting it into the equation</em>
<em />
<em> d y / x = m λ is: </em>
<em>The expression that gives the location of the bright lines on the screen </em>
