In a Young's double slit experiment, two slits are illuminated with a light of wavelength 800 nm. The line joining A 1 P is perpendicular to A 1 A 2 as shown in the figure. If the first minimum is detected at P, the value of slits separation 'a' will be:
The distance of screen from slits D = 5 cm
Text Solution
Verified by ExpertsThe correct answer is:
C
A 2 P-A 1 P = 
(Condition of minima)
