Week 8

Week 8 Student’s Name Course Instructor Institution Date The two topics discussed this week are both very interesting because they are things we enjoyed when we were younger. It is even more beautiful to be able to understand them at this point. However I don’t have any problems with issues concerning the rainbow. My problem is in the atmospheric optics. I understand that the world has unique optical properties. F optics deal with what one can observe and see how comes the visuals effect depends on how fast light reaches the water surface and how fast it can penetrate the surface. In another word the ocean is not blue in a real sense; it only appears to be blue (Morel & Prieur 2015). Water remains colorless. References Averbukh I. S. & Arvieu R. (2015). Angular focusing squeezing and rainbow formation in a strongly driven quantum rotor. Physical review letters  87(16) 163601. Morel A. & Prieur L. (2015). Analysis of variations in ocean color. Limnology and oceanography  22(4) 709-722.

For the forums in this class, we are going to engage in some “peer-learning.” This is where you all not only get to ask questions, but also provide the answers to the questions! I will be around to make sure your responses are correct and on-topic. I will be looking for everyone to ask a question on a topic you may be struggling with, or you don’t fully understand, or maybe want to confirm your understanding. Please make sure that your questions pertain to this week’s lessons. Topics for this week include the following: properties of light, and atmospheric optics

Then respond to at least two other people’s posts with an answer. Make sure you provide a thorough response! This will make sure you understand while helping someone out at the same time! A win-win for everyone! 🙂

Let me know if you have any questions about this!

Summary:
-Post a question on a topic you are struggling with.
-Respond to at least two other people’s posts.

Instructions: Your initial post should be at least 250 words. Please respond to at least 2 other students. Responses should be a minimum of 100 words and include direct questions.

Student 1Hello class!

It has been a pretty fascinating class and I have thoroughly enjoyed the information that I have learned over the past 8 weeks. Throughout the entire chapter that we ended with, I was drawn towards discussing rainbows because my kids are obsessed with them whenever they occur. While living on the Mississippi coast where it rains more days than there are in a year, we see a fair share of rainbows. Now after some reading I can finally explain how a rainbow occurs or actually how we are even able to see it. Water droplets and sunlight are the key ingredients for this miracle to occur. As the book reads, rainfall needs to be happening in one part of the sky while the sun is shining onto it from another part. What I didn’t realize is we need to be facing the rainbow with the sunlight at our back in order for us to observe a rainbow. So in the morning we would need to be looking towards the west with the sun to our back and in the evening we need to be looking towards the east with the sun to our back. However, the most fascinating part of it all in my mind is that no rainbow you are looking at is the same as someone else is looking at. Whenever a person moves, the light from the rainbow is actually being showing through different raindrops and in turn moves with you. Overall this means unless two people can be in the same spot at the same time, no one is able to observe the exact same rainbow you are able to be observing at that time. In the text, it states a secondary rainbow has colors in reverse to its primary rainbow. My questions is, if there is a third rainbow will it reverse the secondary rainbow and show the exact color alignment as the primary? Adam

Class,

As this is our last week of class, I just want to wish you all the best of luck in your degree plans and career endeavors. This week’s lesson was interesting but unexpected. Outside of a rainbow, I have never given much thought to our atmospheres effect on light. Having trained on NVGs I learned about how much ambient light the moon and stars provide to facilitate their function. But phenomena such as sun dogs and pillars were new to me. Sun dogs being produced when ice crystals are struck by the sun’s rays near sunset. I knew that the human eye is sensitive to blue light because, that is the kind of light coming from my iPad, and apparently you’re not supposed to stare at it before bed. This sensitivity resulting in what we see as a blue sky, the same reason that we see the oceans as blue?

Cheers
