The bending of a ray of light also occurs when light passes into and out of a glass lens. ... Because a convex lens can cause rays of light to converge, it can produce an image on a screen.
V o - initial velocity v = velocity at the maximum height, v² = v o² - 2 g h v = 0 0 = v o² - 2 g h v o² = 2 g h = 2 · 9.80 · 0.460 v o² = 9.052 v o = √9.052 = 3.004197 m/s ≈ 3 m/s
