2.Measure the length of the specimen under high power (40X).
What is the relationship between the diameter of the field of view and its power of magnification?
A specimen which fills ¼ of the field of view under an oil immersion lens (1000X) is how long?
A specimen which fills ¼ of the field of view under a scanning lens (40X) is how long?
A specimen which fills ¼ of the field of view under a low power lens (100X) is how long?
