LENSES. 30.1 – Converging & Diverging Lenses. Light is refracted as it passes through glass Converging (Convex) lens – light intersects (converges) on backside, thicker in middle Diverging (Concave) lens – light spreads out (diverges) on backside, thinner in middle.
Focal point = the point that parallel rays of light cross after going through lens
The nerves that carry light information away (optic nerve) produce a blind spot
