Hello!
I'm having a hard time understanding the use of "across" in expressions like those below:
1. "air temperature is uniform across the height and width of any cabinet"...
2. "When the lens is moved across the height"...
It appears that the temperature is uniform along the line representing the height of the cabinet and also along the line representing the width of the cabinet.
In the second case the lens is not crossing the heigh, as I guess, it actually goes along the line.
So, why "across the height"?
Is it something commonly accepted?
Or maybe my understanding of it is wrong?
Please, clarify my doubts.
Thanks
