Question 2 pts
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).
