Todays Lesson: calculating linear Magnification
Lesson Objectives;
Calculating linear increase of cells and organelles by micrographs
, Success criteria
• Define; magnification, image size, actual size.
• Calculate actual size of an object given image size
and magnification.
• Calculate magnification of an object given image
and actual size.
• Calculate magnification of a micrograph using scale
bar method.
• Estimate the size of cells using a microscope image.
• Carry out calibration of a microscope.
, Brainstorm
How to convert mm-μm etc?
, Magnification
• Magnification is the process of enlarging
something only in appearance, not in physical
size.
• This enlargement is quantified by a calculated
number also called "magnification".
• The ratio of the size of an image to the size of the
object
