If the wavelength's given, we can find the distance b/w two consecutive maximas, let it be "S".
Let the screen width be "W".
W = n*S....then [n]+1 will give the no. of maximas.

dsin(theta)=n(lambda) use the constraint of the sine function and find the no of maximas.

jus rem this

for maxima

n_max=[d/Î»] [.] is gif

total maximas =2n_max+1

fo minima

n_min=[dÎ»+12]

total mimima =2n_min
