A thin film of polystyrene is employed as an antireflective coating for fabulite (termed as the substrate). The index of refraction of polystyrene is around 1.49, and the index of refraction of the fabulite is around 2.409. Determine the minimum t
Some HBr was admitted into an evacuated 2000cm 3 vessel in an experiment conducted at a fixed temperature and when the equilibrium was attained some had decomposed yielding the 6.32 mol of bromide as one product.
After the particles pass via the slit they spread out over a range of angles. The de Broglie wavelength of each and every particle is l = 561 nm. Employ the Heisenberg uncertainty principle to find out the minimum range of angles.
Determine the new thickness of the film when we would like green light (wavelength = 560 nm) to be constructively reflected rather.
