    What physics causes this mirror reflection?

    Hi, Thanks to all for your comments Redbelly98 - a good comment about the sum of intensities. I crudely measured reflectivity at less than 50% with transmission around 80%, much closer to "sum not greater than 100%" Crudely = DSLR+digitally generated image of bands of grey which I also...

    What physics causes this mirror reflection?

    Hi, I just bought an iPad mirror screen protector and I'm really puzzled about how it works. You can see a video of the protector here The mirror quality is very good, of the order of 95% reflectivity, and it's not a metalized film as transmission is ~95% You can see in the video that...
