Q16: Separation between bright fringes of parallel beam
A parallel beam is light of wavelength `4.5 × 10^-7 m` is incident on a pair of slits that are `5.0 × 10^-4 m` apart. The interference pattern is focused on a screen `2.0 m` from the slits. The separation between two adjacent bright fringes is most nearly.
`λ = 4.5 × 10^-7 m`
`d = 5.0 × 10^-4 m`
`L = 2.0 m`
Equations:
`λ = (dx)/L`
`=>`
`x = (λL)/d`
`x = ((4.5 × 10^-7 m)(2.0 m))/( 5.0 × 10^-4 m)`
`x = 1.8 × 10^-3 m`
