This article shows us how these butterflies called the glasswing butterflies, have low-reflection wings and because of this, the butterflies become much harder to see.
Air conditioning wastes 15% of our energy any year but scientists think they have found a solution, mirrors! Mirrors can reflect light which is heat and by mounting mirrors on rooftops the light heat can be reflected back into space keeping our homes cooler. If scientists develop enough mirrors like these, in the future we will be able to use a wall of mirrors to keep the scorching suns heat out of our homes!
" “Color” is determined by the wavelength of a stream of light, by detecting the wavelength of incoming light, the eye can determine what color it is looking at. The (normal) eye contains 3 types of cone cells, each containing a different pigment:
The L-cone detecting long wavelength light (peaking in the yellows – but also responsible for reds).
The M-cone detecting medium wavelength light (peaking in the greens).
The S-cone which detects short wavelength light (peaking with blue).
Your brain determines what color it is seeing by observing the ratio between the signals it receives from each of the three types of cones. Color blindness occurs when one or more types of cones are either totally absent, or has a limited spectral sensitivity"
I found this article interesting because it explains the concept of color blindness really simply. It reminded me that colors are made from the same base colors, just in different proportions, the fact that our brain is able to detect and distinguish that is really cool but it also highlights that human eyes are really sensitive and damage can be fatal.
I read an article about a new kind of glasses with retroreflectors in them. Funded by Kickstarter, the glasses use cut prisms to reflect light rays parallel to their incidence. Called "Reflectacles," they are being marketed for use in both safety (night time pedestrians and cyclists) and identity protection (stopping security cameras from seeing your face.) Retroreflector technology is also used in road signs and reflective vests, things that we see every day.
This article summarizes what we learnt in class. The paragraph explains that the normal is perpendicular to the plane mirror and the incident and reflection rays have the same angle. The picture show us the difference of how light reflects on plane and rough surfaces and also explain a couple of things related to this topic.The paragraph also explains the laws of reflection.
Here are 50 photographs of beautiful landscapes. Except, they've been reflected on still water. The still water allows the light rays to reflect in the same direction, causing the reflection on the water to be a non-distorted image.
This articles states that, mirrors aren't the ones who are reversing images, rather it's us doing the flipping. Photons go towards the mirror, and bounce off it. The image of everything beyond the mirror is reflecting backwards, going through the same path it traveled to get their.
Write something about yourself. No need to be fancy, just an overview.
