Question

a tank of water u = 1.33 is 4 cm deep how deep does it appears when seen normally​

Answer 1

Explanation:

$\huge\color{blue}\boxed{\colorbox{cyan}{Answer:➝}}$

${\bold{\sf{Given \: that \: real \: depth \: is \: 4cm}}}$

${\bold{\sf{Refractive \: index \: of \: water \: = \: 1.33}}}$

$\\ {\bold{\sf{\underline{\underline{\red{We \: know \: that \: refractive \: index \: = \frac{Real Depth}{Apparent Depth}}}}}}}$

${\bold{\sf{→ Apparent \: Depth \: = \: \frac{Real \: Depth}{Refractive \: Index}}}}$

${\bold{\sf{Here \: given \: that,}}}$

${\bold{\sf{→ \: Real \: Depth \: = \: 4 cm \: and \: Refractive \: Index \: = \: 1.33}}}$

${\bold{\sf{→ \: Apparent \: Depth \: = \: \frac{4}{1.33}}}}$

${\bold{\sf{→ \: Apparent \: Depth \: = \: 3 cm}}}$

${\large{\tt{\underline{\fbox{\purple{Hence, the tank looks 3cm deep when look from outside }}}}}}$
