The phase shift between ordinary and extraordinary waves in the plastic and thus the
degree of transmission is dependent on both the birefringence An (= no-ne), and the
air wavelength 20:
Ap= (nod-ned) (2π/20)
where the symbols have their usual meaning.
If we have a situation whereby, at a particular region in the plastic, for blue light (20=
450nm) the phase shift is 47 and the blue light is not transmitted, at what wavelength
will the phase shift be 3r, where the transmission will be a maximum? What will
happen to the blue light if we rotate one of the polarisers so that the transmission
axes of the two are now parallel?
Sources A and B emit long-range radio waves of wavelength 380 m, with the phase of the emission from A ahead of that from source B by 90°. The distance rA from A to a detector is greater than the corresponding distance rB from B by 140 m. What is the magnitude of the phase difference at the detector?
Two interfering light waves have intensities of 20\,W\,m−2 and 40\,W\,m−2, and the phase difference between them at some point P is π/3. The intensity at P, in W m−2−2, including interference is:(give your answer as a decimal to 1 d.p. )
