Question

Anyone? please.....Class 10
Light - reflection and refraction​

Answer 1

Answer:

we know that ,

refractive index = real depth/apparent depth

refractive index pf colourful liquid =300/300-90=30/21

refractive index=10/7 or 1.42( Approximately)

relative refractive index of water with respect to the liquid,

$= \frac{ \frac{4}{3} }{ \frac{10}{7} } \\ = \frac{4 \times 7}{10 \times 3} \\ = \frac{28}{30} \\ = \frac{7}{10} \\ = 0.7$

This may be the correct answer...
