Question 64
XE-CNAT2 marksNeeds review
A new glass material is developed to minimize the transmission of the light through the window with glass panel of thickness 5 mm. The refractive index of the glass material is 1.5 and the absorption coefficient can be changed from 0.3 cm⁻¹ to 1 cm⁻¹. In the given range of absorption coefficients, the ratio of the maximum to the minimum fraction of the light coming out of the other side of the glass panel is ________. (Round off to two decimal places)
