Problem - What's the difference between reflection and refraction?
hypothesis - !?!?!?!?
please helP!!!
i understand that you don't get this question but let me explain it to you
do today my science teacher was showing us some experiments about reflections and refractions and we were suppose to take notes (which i did)
so here's an example
we roll a paper, look inside the paper through the hole and then we bring our hand on the side
can you see a hole in your hand?
another one is when she put a pencil in a beaker
inside the beaker we see the pencil bigger but looks broken so it's refraction
i to create a lab base on what we saw today
the thing is that i have NO IDEA to write for my hypothesis
the problem is what's the difference between reflection and refraction?
plzzzzzzzzzzzzzzz helppppp

Don't worry, I'm here to help! Let's start by understanding the concepts of reflection and refraction, and then we can compare the two.
Reflection is the bouncing back of light or any other wave when it hits a surface through which it cannot pass. When light strikes a surface, such as a mirror or a still water surface, it reverses its direction and returns to the same medium it came from. This phenomenon occurs because the angle of incidence (the angle between the incoming light ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected light ray and the normal).
Refraction, on the other hand, is the bending of light or any other wave when it passes from one medium to another. When light travels from one medium (like air) to another medium (like water or glass), its speed changes, causing it to bend. This bending is due to the change in the velocity of light as it enters a different medium. The amount of bending is determined by the angle at which the light approaches the boundary between the two media, which is known as the angle of incidence, and the properties of the media involved.
Now, to understand the difference between reflection and refraction:
1. Different Path: In reflection, the light wave does not enter or pass through the medium it encounters. Instead, it bounces off the surface and travels in a different direction. In refraction, the light wave passes from one medium into another, causing it to bend and change its direction.
2. Speed Change: Reflection does not involve any change in the speed of light since the light remains within the same medium. In refraction, the speed of light changes as it enters a different medium, resulting in bending.
3. Angle Relations: In reflection, the angle of incidence is equal to the angle of reflection. In refraction, the angle of incidence is different from the angle of refraction.
Remember, this explanation provides a general understanding of reflection and refraction. With further exploration and study, you can delve deeper into the intricacies of these phenomena.
