Question

If the angle between the normal and the incident ray is 30°, the angle between the incident and the reflected ray will be
(1) 60° (2)30° (3)0° (4)90°​

Answer 1

$\huge\sf☯ Answer:$

60°

$\huge\sf Explanation:$

If the incidence Angle is 30° so the reflected angle will also be 30° and to find the angle between incident ray and reflected ray we have to add both angles:-

$\sf \angle \: e = \angle \: r \\ \sf\angle \: e + \angle \: r = \: required \: angle \\ \sf 30 \degree + 30 \degree = required \: angle \: \\ : \implies 60 \degree$

Answer 2

$\huge{\underline{\red{\mathfrak{♡ANSWER♡}}}}$

If the incidence Angle is 30° so the reflected angle will also be 30° and to find the angle between incident ray and reflected ray we have to add both angles:-

\begin{gathered} \sf \angle \: e = \angle \: r \\ \sf\angle \: e + \angle \: r = \: required \: angle \\ \sf 30 \degree + 30 \degree = required \: angle \: \\ : \implies 60 \degree\end{gathered}

∠e=∠r

∠e+∠r=requiredangle

30°+30°=requiredangle

:⟹60°
