Answer:
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

Answer:
48 cm²
Step-by-step explanation:
Let the height be x cm, then length of each equal side of the isosceles triangle is (x + 2) cm
According to Pythagora's Theorem,
(x + 2)² = x² + 36
x² + 4x + 4 = x² + 36
4x = 32
x = 8
area = 1/2 x base x height
= 1/2 x 12 x 8
= 48 cm²
