When a light ray travels from denser to rarer medium- then the angle of incidence for which the refracted ray becomes parallel to the interface-x2220-r-90-x2218- is known as critical angle for that pair of media-xA0-Here- the denser medium is Glass -x3BC-g-53-amp-the rarer medium is water -x3BC-w-43

If the refractive index of water is 4/3 and that of glass is 5/3, then the critical angle of light entering from glass into water will besin−1(45)sin−1(34)sin−1(12)sin−1(23)

When a light ray travels from denser to rarer medium, then the angle of incidence for which the refracted ray becomes parallel to the interface(∠r=90∘), is known as critical angle for that pair of media. Here, the denser medium is Glass μg=53&the rarer medium is water μw=43

If the refractive index of water is 4/3 and that of glass is 5/3, then the critical angle of light entering from glass into water will be
${sin}^{- 1} (\frac{4}{5})$
${sin}^{- 1} (\frac{3}{4})$
${sin}^{- 1} (\frac{1}{2})$
${sin}^{- 1} (\frac{2}{3})$
