If the 8th bright band of wavelength $λ_1$ coincides with 9th bright brand of wavelength $λ_2$ in a Young's double slits experiment then the possible wavelength of two lights are: |
$λ_1=450 nm, λ_2=400 nm$ $λ_1=400 nm, λ_2=450 nm$ $λ_1=425 nm, λ_2=450 nm$ $λ_1=400 nm, λ_2=425 nm$ |
$λ_1=450 nm, λ_2=400 nm$ |
The correct answer is Option (1) → $λ_1=450 nm, λ_2=400 nm$ |
