a drawing would be helpful.

Answer 1

To draw:

Ray diagram to locate the image of a point object O placed in front of an equilateral prism such that its vertex is pointing upwards.

Solution:

$\star$ Follow the steps:

• First we draw an equilateral Triangle placed on the floor and a point object present on the left side of the equilateral triangle.

• Incident Light rays from the object will undergo refraction at the first surface to form the refracted ray.

• The refracted Ray will again undergo refraction at the second surface and deviated towards the floor on the right side of the prism. This ray will be called emergent ray.

• Extend the emergent ray until it it crosses the principal axis; the point of intersection with the principal Axis will denote the position of the image.
