MCQ
There are two sources kept at distances $2 \lambda$. A large screen is perpendicular to line joining the sources. Number of maximas on the screen in this case is $(\lambda=$ wavelength of light $)$
- A$1$
- B$3$
- ✓$5$
- D$7$
$\Delta xmax =0$ and $\Delta xmax =2 \lambda$
Theortical maximas are $=2 n+1=2 \times 2+1=5$
But on the screen there will be three maximas
