Two slits are made one millimetre apart ...

Two slits are made one millimetre apart and the screen is placed one metre away. What is the fringe separation when blue-green light of wavelength 500 nm is used ?

Text Solution

Verified by Experts

Distance between two consecutive bright or two consecutive dark fringes is called "fringewidth". Its symbol is B. Its formula is :
`beta=(lamdaD)/(d)`
`:.beta=((500xx10^(-9))(1))/((1xx10^(-3)))`
`:.beta=5xx10^(-4)m`
Two slits are made 1.33 mm apart and the screen is placed 1.33m away. What is the fringe seperation when blue-green light of wavelength 630 nm is used ?
