Physics - Geometrical Optics Question with Solution | TestHub

Given,

Angle of prism, $A=1°$

Refractive index of prism, $\mu =1.5$

For this prism, minimum angle of deviation is given by

$\delta =(\mu -1)A$

$\Rightarrow \delta =(1.5-1)\times 1°=\frac{1}{2}=\frac{5}{10}=\frac{N}{10}$

$\Rightarrow N=5$
