Define each of the following wave phenomena, and give an example of where each occurs: (a) refraction;
Svetach [21]

Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.

<h3>What causes wave refraction?</h3>

Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.

<h3>What characteristics does a wave have?</h3>

The following characteristics of waves:

  • Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
  • Waves may speed up or slow down as they transition from one medium to another at an angle.

Write any three reason for the profuse use of plastic . although it is harmful .​
Phantasy [73]
(1)Plastics (i.e. synthetic polymers) are used frequently for many applications because they tend to be (a) easy to fabricate items with, by moulding, or other methods, (b) can be strong even though very lightweight, so useful for making items that require good physical strength, as well as things like packaging which need to be able to support the contents correctly, (c) relatively low cost (especially overall, when ease of fabrication is taken into account.
(2)The "use" of plastics is not harmful per se, and plastics themselves are innocuous (one reason that they fail to readily biodegrade is that they do not interact with biological systems). But poor manangement of waste plastic can lead to problems.
(3)Failing to recycle and reuse synthetic polymers can lead to those items not landfilled (which is a separate issue - ultimately we would run out of landfill sites) items ending up in the sea, rivers or in the general environment where they can be hazardous to wildlife, and look unsightly.
But that is down to poor management, and societal attitudes, not down to the fact that the items are made of plastics.
(4)If we failed to manage sewage and simply discharged that into the streets or into rivers that would be a major problem too. But that doesn't mean we should "ban sewage" - just manage it in an effective way.
