A glass plate 2.50 mm thick, with an index of refraction of 1.40, is placed between a source of light with wavelength 540 nm (in vacuum) and a screen. The source is 1.80 cm from the screen.
How many wavelengths are there between the source and the screen?
(HINT: the wavelength of light inside the glass is different!)
Answers: 2
thickness of the glass plate, 
wavelength of the source light,
