In a Young's double slit experiment, two narrow vertical slits placed 0.800 mm apart are illuminated by the same source of yellow light of wavelength 589 nm. How far are the adjacent bright bands in the interference pattern observed on a screen 2.00 m away ?

Text Solution

Verified by Experts

The correct Answer is:
A, D
Given that `d=0.8mm=0.8x10^-3m`
`lamda=589nm`
`=589xx10^-9m and d=2m`
so, `beta=(Dlamda)/d=(589xx10^-9xx2)/(0.8xx10^-3)`
`=1.47xx10^-3m`
`=1.47mm`
