Figure 1 of 1

Explanation / Answer

distance between two successive bright spots is y

but y = m*lamda*L/d

given that

lamda = 650*10^-9 m

L = ?

d = 0.2*10^-3 m

m = 1

then

y = 1*650*10^-9*L/(0.2*10^-3)

0.5*10^-2 = 1*650*10^-9*L/(0.2*10^-3)

L = (0.5*10^-2*0.2*10^-3)/(1*650*10^-9)

d = 1.54 m
