Light of wavelength 465 nm passes through a single slit of width 2.32*10^-5 m. At what angle does the first interference minimum (m=1) occur?

1.15°

Explanation:

The width of slit,  angle of interference and wavelength are related with the formula

and making

 the subject of formula we get

Where

 is the angle where the first interference occurs,  w is width,

  is the wavelength

Substituting 1 for m,   for w and  for

Therefore,  rounded off,  the angle is approximately 1.15°
