Question

The student sees the following and measures the length of the amoeba specimen as shown by the red line on the image below:

                                        

The student has recorded the number of ocular divisions measured as 35. Show how the true size of the specimen would be calculated in terms of micrometres.  

Answer 1

10 spaces on the ocular micrometer = 1 space on the stage

1 increment on the stage micrometer=0.01mm

1 increment at 35x = 35μm
