Answer:
(A). The order of the bright fringe is 6.
(B). The width of the bright fringe is 3.33 μm.
Explanation:
Given that,
Fringe width d = 0.5 mm
Wavelength = 589 nm
Distance of screen and slit D = 1.5 m
Distance of bright fringe y = 1 cm
(A) We need to calculate the order of the bright fringe
Using formula of wavelength
Put the value into the formula
(B). We need to calculate the width of the bright fringe
Using formula of width of fringe
Put the value in to the formula
Hence, (A). The order of the bright fringe is 6.
(B). The width of the bright fringe is 3.33 μm.
