A convex lens is thicker in the middle than at its edges and converges parallel rays of light that pass through it, bringing them together at a focal point.
congrats on reading the definition of Convex lens. now let's actually learn it.
Focal Point: It is the point where parallel rays of light converge or appear to diverge after passing through a lens.
Focal Length: This is the distance between the center of a lens and its focal point. It determines how strongly a lens converges or diverges light.
Converging Lens: A convex lens is also known as a converging lens because it brings parallel rays of light together at a focal point.
