A right-angle crown glass prism with critical angle `41^(@)` is placed berore an object, `PQ`, in two position as shown in the figure `(i)` and `(ii)`. Trace the paths of the rays from `P` and `Q` passing through the prism in the two cases.

A right angled crown glass prism with critical angle 41^@ is placed before an object PQ in two positions are shown in figure SAQ 29 (a) and (b). Trace the path of the ray P and Q passing through the prisms in the two cases.

A ray PQ is incident normally on the face AB of a triangular prism of refracting angle of 60^(@) , made of a transparent material of refractive index 2/sqrt(3) , as shown in the figure. Trace the path of the ray as it passes through the prism. Also calculate the angle of emergence and angle of deviation.

A ray PQ is incident normally on the face AB of a triangular prism of refracting angle of 60^(@) , mae of a transparent material of refractive index ( sqrt(3))/( 2) , as shown in the figure. Trace the path of the ray as it passes through the prism. Also calculate the angle of emergence and angle of deviation.

The angle Of a prism is 60 degree. What is the angle of refraction for a ray passing through the prism in minimum deviation position
