I'm Luke from North-East England. I'm 20 years old and I love Doctor Who, among most other things on tumblr.
As this is very a brief description of me and I like to talk to people, feel free to ask stuffs!
it’s really funny bc like listening to english majors talk about their classes or projects theyre really articulate and they use complex words and stuff and it’s very prestigious sounding and then you listen to science majors and if theyre just talking amongst themselves it sounds more like “yeah i put the compound in the thing and honestly i was hoping for a little boom but all i got was a sizzle i dont know what i did wrong.”
Here you can see the light from a laser being bent as it follows the path of a stream of flowing water. This happens because the angle at which the light from the laser hits the surface of the water is beyond the ‘critical angle’ - instead of refracting the light, it’s reflected internally. This ‘total internal reflection’ is a property used in fibre optic cable to transmit signals of light over great distance, allowing light to bend around corners. To see how you can do this demonstration for yourself & for an answer to the question: what colour is a mirror? Check out this video: http://youtu.be/woN9KpAGv4I
