A glass sheet 1.40 ?m (micrometer) thick is suspended in air. In reflected light, there are gaps in the visible spectrum at 538 nm and 615.00 nm. Calculate the minimum value of the index of refraction of the glass sheet that produces this effect. n=? Please show your work and explain the equation. Thanks!
