I What does "upright" mean in geometric optics?

Click For Summary
An "upright" image in geometric optics refers to an image that maintains the same orientation as the object, as opposed to an "inverted" image, which is flipped upside down. Additionally, "laterally inverted" describes an image that is reversed from left to right. These terms help categorize images formed by lenses and mirrors based on their orientation relative to the object. Understanding these concepts is essential for studying image formation in optics. Clear definitions of these adjectives enhance comprehension of geometric optics principles.

A quick Google will straighten that out for you.

Hint: the opposite of 'upright' is 'inverted'.

Also ‘laterally inverted’ is a good description in many circumstances. All three terms are probably easier to recognise than to describe.😉
 

Thread 'Why would an atmosphere without greenhouse gasses be colder than with them?'

Quick question that I haven't been able to find the answer to. Greenhouse gasses both warm and cool the atmosphere by slowing heat loss to space. But what would happen without GHGs? I read that the earth would be colder (though still relatively warm), but why? Without GHGs the atmosphere would still be a similar mass and still warmed by conduction from the surface, yet without a means to radiate that heat to space. Why wouldn't the atmosphere accumulate heat over time, becoming warmer? How...
