Two Beam Interference can be used to create two Virtual coherent light sources and observe interference phenomenon. Monochromatic light in these experiments is produced by sodium light source or He-Ne laser. The wavelength (λ) can be determined by the formula, All uprights are Mounted on specially designed hexagonal optical bench with locking arrangements for precise positioning.
