Resolution and contrast are two critical factors that influence your ability to
see an object. Explain each.
Your Answer:
Resolution is the distance between two objects in which the objects can still
be seen as separate. A poor resulution will result to two or more objects
appearing as one
Contrast is the difference in light absorbance between two objects. Whe
there is poor contrast, it results to a high bacground and makes visualization
difficult because you are unable to contrast between the background and the
object you are observing. For example poor contrast is illustrated by looking
at two dark objects in the dark which makes it difficult unlike looking at dark
coloured objects in bright sunlight; this is a good contrast
Resolution refers to the distance between two objects at which
the objects still can be seen as separate. Poor or low resolution
means two (or more) objects may appear as one.
Contrast is the difference in light absorbance between two
objects. Poor contrast gives a high background and makes the
visualization of multiple objects difficult. For instance, trying to
identify 2 dark colored objects at night (low light = low contrast)
versus the same 2 objects in the middle of a sunny afternoon
(bright light against 2 dark objects = high contrast).
