The biggest delta means - the highest mountain compared to the lowest valley.
On earth for example it's around 20 km(everst ~8km, deepest point in coean ~11km).
The estimation should be of course as a function of the radius, and maybe some other parameters.

its fairly obvious that you wouldnt see anything without a light and if you had a light because the light couldnt escape does that mean it would become increasingly brighter? or hotter? or perhaps it wouldnt because i would be in the way. I guess it depends on what sort of light source and other variables like size of sphere, quality of mirror etc. It has to be a hyperthetical question anyway. I asked the same question a few days ago and I had some good answers but most were guessing like myself I still cant get my head round it. thanks, ps anyone got a picture of themselves in a mirrored sphere or perhaps the camera flash had an undesirable effect.

Through respiration and photosynthesis, seagrass acquired oxygen and release it back to the environment. The leaves and roots have special tissues that aids these process. What is the function of aerenchyma and lacunae? What is the function of the airspaces around the leaves and roots? How does the oxygen uptake and release in seagrass relate to the efficiency of root to absorb nutrients from the surrounding?
