Answer 2

Answer:

hey here is your answer

pls mark it as brainliest pls

Step-by-step explanation:

$so \: let \: the \: refractive \: index \: of \: glass \: be \: G \: that \: of \: water \: be \: W \: and \: of \: air \: be \: A \\ so \: we \: know \: that \\ refractive \: index \: (n) = \frac{volume \: of \: first \: object \: v1}{volume \: of \: second \: object \: v2} \\ \\ so \: according \: to \: first \: condition \\ 1.22 = \frac{W}{ G } \\ ie \: \: G = \frac{W}{1.22} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (1) \\ \\ according \: to \: second \: condition \\ 1.5 = \frac{A}{G} \\ ie \: \: G = \frac{A}{1.5} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (2) \\ \\ equating \: both \: equations \: \\ we \: get \\ \frac{A}{1.5} = \frac{W}{1.22} \\ ie \: \: \: \frac{A}{W} = \frac{1.5}{1.22} \\ = 1.2295 \\ = 1.22 \\ = 1.2 \\ \\ hence \: \frac{A}{W} = 1.2 \\ \\ hence \: the \: </p><p>refractive \: index \: of \: water \: with \: respect \: to \: air \: is \: 1.2$
