A thin layer of glass (n = 1.50) floats on a transparent liquid (n = 1.34). The glass is illuminated from above by light with a wavelength, in air, of 5.80 x 102 nm. Calculate the minimum thickness of the glass, in nanometres, other than zero, capable of producing destructive interference in the reflected light. Draw a diagram as part of your solution
