Answer:

Explanation:

Answer:

The slits are 246 and 62 wavelengths wide, respectively.

Explanation:

Given that there are two slits:

the largest slit = x1 = 0.16mm or 0.00016m wide

the smallest slit = x2 = 0.04mm or 0.00004m wide, and

the wavelength of laser light = λ = 650nm or 650 × 10˄—9m

(a) the largest slit is X wavelengths wide where X = x1/ λ

Therefore, X = 0.00016m/650 × 10˄—9m = 246 wavelengths

(b) the smallest slit is X1 wavelengths wide, where X1 = x2/ λ

Therefore, Y = 0.00004m/650 × 10˄—9m = 62 wavelengths
