Answer :
Answer:
300 and 600
Explanation:
Using the 30× objective lens:
=
Ocular lens
×
Objective lens
M=Ocular lens×Objective lens
=
20
×
30
M=20×30
=
600
M=600
So, with the 30× objective lens, the total magnification is
600
600
.
Using the 15× objective lens:
=
Ocular lens
×
Objective lens
M=Ocular lens×Objective lens
=
20
×
15
M=20×15
=
300
M=300
So, with the 15× objective lens, the total magnification is
300
300
.
Therefore, depending on which objective lens is in use (either 30× or 15×), the total magnification of the microscope will be either
600
600
or
300
300
, respectively
