Why does a converging lens behave as a burning glass?

Answer 1

Convex lenses focus parallel light rays from distant sources such as the sun to a single point on the principal axis of the lens. This point is called the principal focus of the convex lens. A source such as the sun is producing enough energy to heat a substance if it is placed at the principal focus point.

Answer 2

A converging lens can behave like a burning glass because it can focus parallel light rays to a single point called the focal point. When sunlight passes through a converging lens, the lens can concentrate the light rays onto a small spot, causing the temperature to rise and potentially ignite flammable materials placed at the focal point. This concentration of light energy is similar to how a magnifying glass concentrates sunlight to create a focused beam.

Answer 3

Because is converges the light and focus it
