Hi. I'm a retired several-sciences guy, a STEM Ambassador encouraging kids to look at science, hopefully fostering interest.
I'm also interested in microscopy.
I/we are looking for ideas for small items which demonstrate interesting/educational things, for kids to look at through microscopes...
Hi team of experts,
Firstly, I'm not a physicist so apologies for the high level of ignorance.
How do ultrosonographic images work? Let's assume I want to observe dynamic changes within a specific area of the body. What type of dynamic changes are detected on those images?
Normally I use the little "cute sunset image" icon on the rich text editing bar to include photos in a post (it's the icon to the right of the smilie icon and to the left of the film frame icon). And normally, no problem.
However, for the post below, I am finding that no matter what I do...
the question in my exam goes like this:
should we use a thick convex mirror or a thin one for the anti-theft mirror?
the given answer:
thin, because a thin convex mirror does not form multiple images
can someone please explain to me why a thin spherical mirror does not form multiple images...
