A concave lens is thinner at the centre than at the edges. Concave lenses are thinner 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. The distance between the principal focus and the centre of the lens is called the focal length.

Basketball players are known for being tall, but even among giants this 18-year-old player manages to stand out. Prep player Tacko 'Taco' Fall is 7ft 5in tall, which would make him the tallest player in the NBA if he signed up today, topping Oklahoma City centre Hasheem Thabeet by two inches. He wears size 22 shoes - the same as Shaquille O'Neal - eats entire pizzas covered with chicken and hamburger to keep his 18-stone weight up, and has an 8ft wingspan.
