In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 609 nm. An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.69 m and the distance between the two slits is 0.118 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the sixth-order maximum (bright fringe) on the screen?

Answer:


\Delta x = 3.65 \mu m

Step-by-step explanation:

As we know that the sixth order maximum will have path difference given as


\Delta x = N\lambda

here we know that

N = order of maximum


\lambda = 609 nm

now we have


N = 6

so we know that


\Delta x = 6(609 nm)


\Delta x = 3.65 \mu m
