Given information
light of wavelength 670 nm is incident normally,
number of dark bands=24
Step-by-step explanation
Step 1.
For a thin film, dark fringes will occur when
2 t = m -----------------(1)
as m = 0 corresponds to the points where the plates meet,
( m + 1 ) represents the number of fringes.
Hence m+1 = 24
m=24-1
m=23
