Question

what happens to light when it hits a curved surface?

Answer 1

Answer:

The bending of a ray of light also occurs when light passes into and out of a glass lens. However, because of the curved surfaces of the lens, the bending causes the light rays in a beam either to come together (converge, picture on left-hand side) or to spread out (diverge, picture on right-hand side).

Answer 2

• Refraction
• $\sqrt{5}$
• $\sqrt{3} {}^{2}$
• of light at plane surface
