Question

Define image and write 1 difference between convex and concave lens

Answer 1

Convex lenses are thicker at the middle. ... Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.
