1. [25] Blue light waves { 3* =0.4 l1 m) from the sun at right angles to an innite thickness glass with a refractive index of 1 .4 If you join the company, (a) Find the optical power reflectance of the glass surface as %. [5] {b} Explain how to make blue light waves 100% incident on the glass without reflection. [10] {c} Green light waves { 3* =0.5 l1 m) from the sun are also incident at the same (it: as blue light waves Give a solution. [10]
