Question

Green light (λ = 566 nm) strikes a single slit at normal incidence. Part A

What width slit will produce a central maximum that is 3.00 cm wide on a screen 2.00 m from the slit?
Express your answer to three significant figures. (Unit for answer is μm ) (Find W)

Answer 1

755 x 10⁻⁷ m

Step-by-step explanation:

D = distance of screen

=2. m

d is width of slit = ?

wave length λ = 566 nm

Width of central maxima = 2 λD /d

= 3.00 x 10⁻² =2 λD /d

`d=(2*566*10^(-9)*2)/(3*10^(-2))`

= 754.67 x 10⁻⁷ m .

= 755x 10⁻⁷ m
