Question:medium
Figure shows the graph of angle of deviation \( \delta \) versus angle of incidence \( i \) for a light ray striking a prism. The prism angle is
![angle of deviation δ versus angle of incidence i]()
Figure shows the graph of angle of deviation \( \delta \) versus angle of incidence \( i \) for a light ray striking a prism. The prism angle is
![angle of deviation δ versus angle of incidence i]()
Show Hint
In prism experiments, the minimum deviation occurs when the ray passes symmetrically through the prism, and the angle of incidence is at its minimum.
