select the correct answer.\nthe light incident on a smooth reflecting surface undergoes specular reflection. the angle of reflection is 55°. what can you say about the angle of incidence?\na. its greater than 55°.\nb. its less than 55°.\nc. its equal to 55°.\nd. it could be any angle between 0° to 90°.
Answer
Explanation:
Step1: Recall law of reflection
According to the law of reflection, the angle of incidence ($\theta_i$) is equal to the angle of reflection ($\theta_r$), i.e., $\theta_i=\theta_r$.
Step2: Substitute given value
Given $\theta_r = 55^{\circ}$, then $\theta_i=55^{\circ}$.
Answer:
C. It's equal to 55°.
