Can someone give an answer ASAP:-)
3. magnification = image size / object size

30 micrometers = 0.003cm

3/0.003 = 1000

Object size = image size/magnifcation

3/1000 = 0.003cm

= 30 micrometers / 0.003cm

Thank you! You really helped me!
I’m struggling on one more question (lol) which I’ve posted on another thread! Could you please answer that one as well with working out!
Regards.
