Question 46 The refractive index of flint glass is 1.65 and that for alcohol is 1.36 with respect to air. What is the refractive index of the flint glass with respect to alcohol ? (A) 0.82 (B) 1.21 (C) 1.11 (D) 1.01 Given, Refractive index of flint glass w.r.t air = 1.65 Refractive index of alcohol w.r.t air = 1.36 Now, Refractive index of flint glass w.r.t alcohol = (๐‘…๐‘’๐‘“๐‘™๐‘Ž๐‘๐‘ก๐‘–๐‘ฃ๐‘’ ๐‘–๐‘›๐‘‘๐‘’๐‘ฅ ๐‘œ๐‘“ ๐‘“๐‘™๐‘–๐‘›๐‘ก ๐‘”๐‘™๐‘Ž๐‘ ๐‘  ๐‘ค.๐‘Ÿ.๐‘ก ๐‘Ž๐‘–๐‘Ÿ)/(๐‘…๐‘’๐‘“๐‘™๐‘Ž๐‘๐‘ก๐‘–๐‘ฃ๐‘’ ๐‘–๐‘›๐‘‘๐‘’๐‘ฅ ๐‘œ๐‘“ ๐‘Ž๐‘™๐‘๐‘œโ„Ž๐‘œ๐‘™ ๐‘ค.๐‘Ÿ.๐‘ก ๐‘Ž๐‘–๐‘Ÿ) = (๐Ÿ.๐Ÿ”๐Ÿ“)/(๐Ÿ.๐Ÿ‘๐Ÿ”) = 165/136 = 1.21 So, the correct answer is (B)
