    Mass Reflection
AI Thread Summary
Mirror reflections and shadows do not have mass, as they are optical images and do not consist of matter. The discussion highlights that asking if these images have mass is akin to questioning if a color has mass. While reflections can appear to interact with physical objects, they remain non-physical entities. The conversation also touches on the elusive nature of ghostly entities, suggesting their absence in scientific experiments. Ultimately, the nature of ghostly entities remains speculative and untestable in a laboratory context.

Does my mirror reflection have mass? What about your shadow?
 
Science news on Phys.org
"Your mirror reflection" is not a well-defined object (same for the shadow). Asking if it has mass is about as meaningful as asking "does the color red have mass?".
 
That makes sense. I am not involved in Physics in anyway, it was just something that I was curious about. Thank you.

Optical images do not consist of matter so the answer has to be no. Interestingly, your image can be seen to bump into other images and knock them over. Now there's a thought. :smile:

O yes that does

damn daemons, they always disappear in a laboratory setting, that's why we can't scientifically conduct experiments on ghosts :wink:
 
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
