Correct answer is C
critical angle formula = \(sin^{-1}\) \(\frac{n_2}{n_1}\)
→ \(sin^{-1}\) \(\frac{1}{1.33}\) = \(sin^{-1}\) 0.7518

Rotational
Translational
Vibratory
Correct answer is C
A couple consists of two equal and opposite forces acting at a separation, so that net force becomes zero. When a couple acts on a body it rotates the body but does not produce any translational motion. Hence, only rotational motion is produced.
