Question

the place where the refracted rays from the convex lens meet on the principal axis is​

Answer 1

Explanation:

The extension of the refracted rays will intersect at a point. This point is known as the focal point. Notice that a diverging lens such as this double concave lens does not really focus the incident light rays that are parallel to the principal axis; rather, it diverges these light rays.

Answer 2

Answer:

The place where the refracted rays from the convex lens meet on the principal axis is focal point.

Explanation:

• The convex lens converge the rays and made it parallel to the principal axis.
• So,it is called as converging lens.
• It is used in eyeglasses.
• The convex lens are thicker at the middle and thinner at the edges.
• A principal axis is defined as a line which is passing through both the curvatures of the lens.
• It can also be defined as the line which connects the two centers of the lens. 
• When refraction occurs, refracted ray is the ray which has entered the second medium and bent either away from the normal or towards the normal depending on the density of the new medium in comparison to the old one. passing through both the curvatures of the lens.
• The point on the axis of a lens or mirror to which parallel rays of light converge or from which they appear to diverge after refraction or reflection is known as focal point.
• It is also known as central point of attention or interest.
