A beam of unpolarized light travels from a denser medium of refractive index ₁ to a rarer medium of refractive index ₂ . If i_p is the polarizing angle (Brewster's angle) for this interface, then which of the following is the correct range for i_p ?

Step-by-step solution

According to Brewster's law, when light travels from a medium of refractive index ₁ to a medium of refractive index ₂ , the polarizing angle i_p is given by (i_p) = ₂ ₁ . Since the light is traveling from a denser medium to a rarer medium, we have ₁ > ₂ . This implies that the relative refractive index ₂ ₁ Therefore, (i_p) Since i_p must be a positive angle, and (45^ ) = 1 , the polarizing angle must lie in the range 0^ Answer: 0^ < i_p < 45^
