Two beams of red and violet colours are made to pass separately through a prism of $A=60°$. In the minimum deviation position, the angle of refraction inside the prism will be,

Assertion: If an object is placed at the centre of a glass sphere, and it is observed from outside. Then, it will appear at the centre itself.

Reason: All rays starting from object fall normal on the surface. Hence, they do not bend.
