First-off:
A camera is essentially a light source(flash) with a circular lens.
When the camera flash activates it sends out light in waves at (v=c), these specific waves have a specific wavelength(In the Visible light EM spectrum as you can see it) that travels from the flash in ALL DIRECTIONS. Now, as a small tid-bit(learn something for a change) the smaller the wavelength the sharper ther picture) This is the chief reason why Electron microscopes are so precise...the wavelength of an electron is VERY small. Anyways, back to making you look foolish. Some of the emited light waves from the flash of the camera hit me, and are recorded optically by the lens of the camera as an image(They essentially bounce back to the camera and are recorded by the lens optically)The light emitted by the flash travels in all directions. The flash does NOT diffract the light beam being emitted from it. It is all-directional not uni-directional. Anyways, the light that has not hit me(In wave format), then hits the mirrors to the left and right of me.(Now remember that the velocity of light waves = c, so the camera mechanism has no chance whatsoever of snapping the initial picture of me formed by the first incoming light waves from the flash, and not also record the after-image formed by the reflections and refractions of the light waves that missed me. So, going right along, the light waves that miss me hit the objects outwith the contours of my body.
Now we come to the optics part of my little dissertation.
There is no such thing as a perfect mirror unless you happen to go by and get an astronomical-grade mirror. Any commercially made mirror is going to have some small refractive index. Doesn't matter how big it is, its still going to be > 1.00, therefore the emitted light waves are going to be refracted back from the mirrors behind me at angles that are (90 - incidence angle) in degrees. So, if a light wave hits the mirror to my right at a 30 degree angle(Sin 30 = 0.866), and the index of refraction is lets just say 1.05(Small but who cares), the incident light wave will be (1.00)sin(30) = (1.05)(sin(x)). Therefore, sin(x) = (1.00/1.05)sin(30) = 0.824 Therefore Sin(Zeta)(0.824) < Sin of Initial incident angle(0.824)....the angle of refraction will be greater than 30 degrees. And from this, the angle of refraction( 90 - incidence angle) will be > 30 degrees relative to the horizontal plane of the mirrors behind me( So about <60 degrees relative to me). Obviously, as the beams of emitted light start to reach (1,2) degrees outwith the contours of my body, the angle of incidence is going to be very big(About 88,89 degrees), therefore, sin(x) is going to approach 1/1.05, which is approx. 0.95. Now the Sin(exp-1) of 0.95 is about near zero(Very close. A couple of degrees). So that means that the angle of reflection BACK to me is (90 - 3(Just an example) = 87 degrees. So, practically, straight right back at me. So, from that little analisis we can conclude that all manner of light waves with different angles of incidence where refracted by the mirror behind me, and therefore BOUNCED back in angles ranging from 3 degrees relative to the horizontal line in front of the camera lens(relative to me both left and right and up and down) to close to 90 degrees(Again..left,right,up, and down). And these light waves where then subsequently CAPTURED by the optical lens of the camera, as an after-image formed by the light waves that missed the optical lens of the camera the first time light was emitted by the flash, but then subsequently where refracted and hit the mirror in front of me(The camera was aimed at the mirror behind me). This is what we refer to in optics as an after-image...and is what generated the sort of twinkling or doubling effect of some of my bodyparts, since I wasn't exactly standing perfectly horizontal to the lens of the camera.
And me saying light bending? Where the heck do you get that from?
I never said that because it has nothing to do with this. Light in a medium not involving a very large gravitational field can only reflect, refract, or diffract(diffraction grating). But in case you're wondering, light CAN bend...due to gravity. Thats Einstein's General Theory of Relativity for your information.
Care to comment on my supposed stupidity now?
I guess not.
I will steamroll right over you each and every time, just to teach you a good lesson. You may think you're smart...but there is ALWAYS going to be, no matter what, someone smarter than you. I learned that my first semester of grad school. Try to engrave that in your memory, so that you're not made to look like a total fool again by somebody else.
And if you're in a top percentile of whatever faculty, it is truly a sad day for the academic community at large.
