physics Test 2 In a double slit experiment, if the separation between the two slits is 0.050 mm and the distance from the slits to a screen is 2.5 m, find the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits.

Respuesta :

Answer:0.015 m

Explanation:

Given

distance between two slits(d)=0.050 mm

Distance between slit and screen=2.5 m

Wavelength[tex](\lambda )=600 nm[/tex]

and distance between First order and second order[tex]=\frac{D\lambda }{2d}[/tex]

[tex]=\frac{2.5\times 600\times 10^{-9}}{2\times 5\times 10^{-5}}[/tex]

[tex]=15\times 10^{-3}[/tex]

=0.015 m
