Two slits are made 1 min apart and the screen is placed 1 m away from the slits. What is the firnge separation when blue green light of wavelength 500 nm is used?

Text Solution

Verified by Experts

`lamda=500xx10^(-9)=5xx10^(-7)m,d=1xx10^(-3)m,D=1m`
`beta=(D lamda)/d=(1xx5xx10^(-7))/(1xx10^(-3))=5xx10^(-4)m`
