Final answer:
The primary difference in reflected waves of glass and water involves their direction, not amplitude, frequency, or velocity. The reflected wave does not change these quantities; it only changes direction when it reflects off the surface. However, in terms of refraction, the wave in glass will undergo more significant bending due to a higher refractive index compared to water.
Step-by-step explanation:
The question pertains to the comparison of reflected waves of glass and water. When a wave is reflected, there is no change in amplitude, frequency, or velocity; instead, there is a change in direction (d. The reflection of a wave is the change in direction of a wave when it bounces off a barrier). Thus, the primary difference will relate to how the wave behaves upon interacting with different mediums.
The speed of light changes depending on the medium it travels through, which affects reflection and refraction. While comparing glass and water, the pattern we see is (c. The speed of light in air > the speed of light in water > the speed of light in glass), indicating that light travels slowest in glass and fastest in air. It is worth noting that when light moves from a less dense to a more dense medium, it bends towards the normal due to a higher index of refraction (c. The light bends toward the normal because the index of refraction of water is greater than that of air). Therefore, when considering refraction, the light wave in glass will experience more significant bending compared to that in water because glass has a higher refractive index than water.
Regarding the amplitude, the question of whether a reflected wave in water or glass has a higher amplitude is more complex and depends on additional factors like the angle of incidence and the specific refractive indices of the materials involved. It's also important to clarify that reflection involves the wave bouncing off a surface, whereas refraction is about the wave bending as it passes from one medium to another (d. Reflected light bounces from the surface whereas refracted light is bent as it travels from one medium to the other).
