Constructive interference is expressed as:
Where d is the separation between the two slits, m is the order, and λ is the wavelength.
For small angles measured in radians, θ ≃ sin θ ≃ tan θ ≃ y/L
Figure Q17.7 shows the viewing screen in a double-slit experiment with monochromatic light.
Fringe C is the central maximum.
What will happen to the fringe if the wavelength of the light is decreased?
