Physics - Geometrical Optics Question with Solution | TestHub

$\delta ={\text{i}}_1+{\text{i}}_2-\text{A}$

$45^{\circ }={\text{i}}_1+{\text{i}}_2-60^{\circ }$

${\text{i}}_1+{\text{i}}_2=105^{\circ }$

${\text{i}}_1-{\text{i}}_2=20^{\circ }$

or$2{\text{i}}_{\text{i}}=125^{\circ }$

${\text{i}}_1=62^{\circ }30^{\prime }\text{, }{\text{i}}_2=42^{\circ }30^{\prime }$
