Hey guys!

My name is Amanda Lutshetu, and I am back for the second instructable that I promised you.I hope that you are going to be as interested in this one as well as you were for the last one.Once you are done looking and understanding this project, please do not forget to leave me a comment.You can also DM me your opinions or any other thing which you may not be clear about.

Now to begin, I conducted this experiment in order to find out whether visible and ultra-violet light varied across different locations.

For the purpose, I again used the XinaBox XK01 kit to conduct this experiment.The XK01 kit can perfom many functions which I believe you saw when you were learning how to assemble the kit and to learn more about it follow the link wiki.xinabox.cc .Once you have your XinaBox XK01 kit with you, please go to the link wiki.xinabox.cc and tap on the search box in the top right corner of the page, and type "getting started XK01" in it. That will direct you to a page which shows all the steps that you need to follow in order to assemble the kit very clearly.

Once you are done assembling your kit you will be good to go.Proceed further by using the kit to collect data and for creating and reading the graphs with the information you receive on Kibana. When you use Kibana you will need to visualize your graphs before creating and using your own dashboard to paste them. Please see the link Introduction | Kibana User Guide[6.6] |Elastic to familiarize yourselves with how to use kibana.

In order to conduct the experiment proficiently make sure that you follow the following steps in order:

Step 2: Report

Proposed Hypothesis:

-Visible and Ultra-Violet light varies across various locations as the sun rays do not hit various locations identically.

Purpose of the Experiment:

-This experiment was conducted in order to find out about the variation of visible and UV light across different locations.

-It was also conducted to bring about an understanding of light properties, wavelengths and sources.

Answers to the Posed Questions:

1. HOW DOES VISIBLE AND ULTRA-VIOLET LIGHT VARY ACROSS SIX LOCATIONS?

-Visible and UV light does vary across different locations, but above all else, we first need to understand that NATURAL light, which produces heat and color, comes from the radiation given off by the sun.Though some artificial lights use gas and electricity to produce light and heat. Unlike natural sunlight, artificial lighting intensity can be adjusted to serve the needs of individual plants.

-Both visible and UV light decrease under a shade, this is because the sun rays do not directly hit this area but the reflection of the sun, however, from the exposed areas do have an effect on the shady area.

-Indoors, we know that we mostly use artificial lights, for instance, light bulbs, but during daytime UV light from the sun may penetrate through our glass windows, as we know that UVA can penetrate a glass.

2. IS THERE A DIFFERENCE IN CHARACTERISTICS BETWEEN NATURAL AND ARTIFICIAL LIGHT? DO ARTIFICIAL LIGHT SOURCES ALSO DIFFER AND HOW?

-As mentioned in the answer above, natural light which produces heat and color, comes from the radiation given off by the sun... some artificial lights use gas and electricity to produce heat and light . Unlike natural sunlight, artificial lighting intensity can be adjusted to serve the needs of individual plants.

-Artificial light is generated by artificial sources, such as incandescent lamps, compact fluorescent lamps (CFLs), LEDs, etc.

-Natural light is the light generated naturally. The most common source of natural light on Earth is the sun.

3. DO THE DIFFERENT WAVELENGTHS OF LIGHT PROPAGATE, REFLECT AND ABSORBED DIFFERENTLY?

-Objects appear in different colors because they absorb some colors (wavelengths) and reflect or transmit other colors. The colors we see are the wavelengths that are reflected or transmitted. Red light is the only light that is reflected from the shirt.

Skills Mastered:

1. After following the steps on assembling the XinaBox XK01 kit, I used it to collect data on both visible and UV light.

2. I followed the link wiki.xinabox.cc to learn how to assemble the XinaBox XK01 kit.

3. I went on and visualized my data before creating graphs and pasting them on my dashboard.

4. I then interpreted all the information given by the graphs into the theory to explain what is happening.

5. This is how I have come up with the abstract we have and all the information already mentioned above.

Required Materials:

. Temperature, Humidity, Pressure, UVA, UVB, UVI, visible light, USB power, Programming unit, Wi-Fi, and OLED display.

Step 3: Abstract

ABSTRACT:

Coming to the last step, we have now reached the conclusion of our abstract, and the good news is that the hypothesis has been confirmed.

- Visible and UV light varies across different locations, this is because the UV rays do not hit different locations with the same UVI (the UV index) hence you will find out that certain areas are cooler than others and that places that receive direct rays from the sun are extremely hot.

-The graphs which I have attached to this experiment prove that visible and ultraviolet light varies across different locations. You will notice that the graph "UVA vs UVB under a shade" flows at lower levels than the amount of UVA and UVB in the graph "UVA vs UVB indoors". This is because indoors we receive light from an artificial source (light bulbs) whereas in shady areas we only get light from the reflection of the areas exposed to the sun.

-The type of light bulbs that gives off UV rays is incandescent and fluorescent bulbs. They both emit UV radiations, but the levels are lower when compared to to reptile basking bulbs or tanning bulb. The strongest source of UV radiation is the sun.
