Question

Deviation of 5° is observed from a prism whose angle is small and whose refractive index is 1.5 . The angle of prism is (A) 7.5° (B) 10° (C) 50 (D) 3.3°

According to the relation δ=(μ-1) A ⇒ 5=(μ-1) A 5=(1.5-1) A A=10°

Q. Deviation of $5^{\circ}$ is observed from a prism whose angle is small and whose refractive index is $1.5.$ The angle of prism is

$7. 5^{\circ}$

$1 0^{\circ}$

$5^{0}$

$3. 3^{\circ}$

According to the relation
$δ = (μ - 1) A$
$\Rightarrow 5 = (μ - 1) A$
$5 = (1.5 - 1) A$
$A = 1 0^{\circ}$

Q. Deviation of 5∘ is observed from a prism whose angle is small and whose refractive index is 1.5. The angle of prism is

7.5∘

10∘

50

3.3∘
