ACTIVITY 5.1 To help you fully understand the wave behavior of electrons, you must first understand the dual nature of light. (10 pts.) Light has a (single, dual) nature. Sometimes, it behaves like a particle called (proton, photon). Light's particle-like traits are best explained by the (photoelectric effect, scattering of light), the theory that (Thomas Young, Albert Einstein) won his Nobel Prize for. . Light also behaves like a wave, which explains how it (reflects, refracts) or how it bounces off in an obstacle. This results in the formation of an (image, object) in a mirrored surface. Light, like any wave, is known to undergo (reflection, refraction) when it passes from one medium to another medium with different optical densities. A light wave will bend (towards, away) the normal when it passes from an optically denser to a less dense medium. . On the other hand, if it is moving from a less dense to a denser medium, the wavefront will bend (towards, away from) the normal
