Activity 2: Reflection and Refraction of Light Refer to the figures to explain how reflection and refraction are explained by the wave and particle models of light. Fill up with the appropriate word/s to give meaning to the paragraphs that follow. Choose from among the words inside the box to complete each sentence. Reflection and refraction are phenomena that are well-explained by the behaviors of light. When a source emits light, its dual property can be observed in different circumstances. Light, as waves, 1) __________ in all directions when emitted. Upon impacting a smooth, specular surface, such as a mirror, these waves

2) __________ or reflect according to the arrival angles. The waves turn back to front as they reflect producing a

3) __________ image. On the otherhand, light can also arrive at the mirror surface as a stream of

4) ____________. Since these are very tiny, a huge number are involved in a propagating light beam. Upon arriving a

5) __________ surface, the particles bounce off in different points so their order in the beam is reversed resulting to a reversed image. A beam of light undergoes

6) __________ when it travels between two media with different refractive indices. Light, as waves,

7) __________ direction upon passing from first medium to second medium. A small portion of each angled

8) ___________ should impact the second medium before the rest of the front reaches the

9) ___________. This part will travel along the second medium while the rest of the waves is still travelling in the first medium. Movement will be

10) __________ through the second medium due to higher refractive index. Since the wavefronts are travelling at different speeds, light will 11) ___________ into the second medium, thus, changing the angle of propagation.​
