Light from a laser with wavelength 400 nm passed through two small openings and produces an interference pattern on a screen 1 m away. If the first point of destructive interference occurs at an angle of 0.1 radians, what is the distance between the two openings?

To solve this problem we will apply the concepts related to destructive interference from double-slit experiments. For this purpose we will define the path difference as,

Here,

= Wavelength

= Angle when occurs the interference point of destructive interference

Our values are given as,

Using the previous expression we have,

Therefore the distance between the two openings is

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6
