An oil flowing on water seems coloured due to interference. For observing this effect, the approximate thickness of the oil film should be

For observing interference in thin films with a light of wave length lambda the thickness of the film :

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 ?

Interference of light is the physcal effect which is produces due to the

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 ?

An oil film (n = 1.45) floating on water is illuminated by white light at normal incidence. The film is 280 nm thick. Find (a) the color or the light in the visible specturm most strongly reflected and (b) the color of the light in the specturm most strongly transmitted. Explain your reasoning.
