Draw a neat diagram to show the refraction of a light ray through a glass prism,and label on it the angle of incidence,and angle of deviation.

(N/A) The refraction of a light ray through a glass prism is shown in the diagram below.
Key components of the diagram:
$1$. $A$ is the apex of the prism.
$2$. $OP$ is the incident ray.
$3$. $i$ represents the angle of incidence.
$4$. $PQ$ is the refracted ray inside the prism.
$5$. $QR$ is the emergent ray.
$6$. $e$ is the angle of emergence.
$7$. $\delta$ represents the angle of deviation,which is the angle between the incident ray and the emergent ray.
