A material having an index of refraction of 1.30 is used as an antireflective coating on a piece of glass `(n = 1.50). What should be the minimum thickness of this film in order to minimize reflection of 500 nm light?

A film with index of refraction 1.50 coats a glass lens with index of refraction 1.80. What is the minimum thickness of the thin film that will strongly reflect light with wavelength 600 nm?

A parallel beam of light of wavelength 560 nm falls on a thin film of oil (refractive index = 1.4). What should be the minimum thickness of the film so that it strongly S4 T z reflects the light ?

A parallel beam of light of wavelength 560 nm falls on a thin film of oil (refractive index = 1.4). What should be the minimum thickness of the film so that it strongly transmit the light ?

A parallel beam of light of wavelength 560 nm falls on a thin film of oil (refractive index = 1.4). What should be the minimum thickness of the film so that it strongly transmit the light ?

A parallel beam of light of wavelenght 560 nm falls on a film of oil (refractive index =1.4 ). What should be the minimum thickness of the film so that it weakly transmits the light ?

Blue light of wavelength 480 nm is most strongly reflected off a thin film of oil on a glass slab when viewed near normal incidence. Assuming that the index of refraction of the oil is 1.2 and that of the glass is 1.6, what is the minimum thickness of the oil film (other then zero)?
