Calculating Refractive Index of a Blade Material Using Microscope Measurements

[Ampavardi]

A blade parallel faces is 5 mm thick. Taken to a microscope it appears that, to pass on the focus of a surface point to a point on the underside of the blade should move the cannon from the microscope 3mm. What is the refractive index of the material it is made the blade?

5/3

Thx

EDIT: Sorry, i can't delete the post now, I'm nwe here e sorry again. I can't read the rules, but now read it.

No need to delete, just please describe what you are aking in a bit more detail. Is this a question, and you are given the answer and asked to show the calculations? Is 5/3 supposed to be the answer? Can you describe how you should approach this problem, and list what the Relevant Equations are?
