Q16.Given below are two statements : Statement I : If the Brewster's angle for the light propagating from air to glass is ๐๐ต, then Brewster's angle for the light propagating from glass to air is ๐ - ๐๐ต. 2 Statement II : The Brewster's angle for the light propagating from glass to air is tan-1๐g, where ๐g is the refractive index of glass. In the light of the above statements, choose the correct answer from the options given below : (1) Both Statements I and Statement II are true. (2) Statement I is true but Statement II is false. (3) Both Statement I and Statement II are false. (4) Statement I is false but Statement II is true.
