Question:-
We are using in class 4.5 mm and 40X.
a) How big is a specimen that takes up 1/2 the field view at 90X?
Step by step
Solved in 2 steps
- Assume your field of view under a 3X objective is 6mm across. What is the field of view in mm under a 20X objective? Show clear work with units for credit. Field of view 20X objective? ___mm What is the field of view of this 20X objective in micrometers? If you observe a specimen under the 20X objective and the specimen spans one-quarter of the field of view distance, how long is the specimen in micrometers?The field of view under the 4x objective is 3.3mm and a specimen looks like they can fit about 10 times across the field of view. What is the size of the specimen?If the field diameter is 2.4 mm and there are 16 cells across the field of view when using the 40X objective, what is the true length of one cell in millimeters (mm)?
- What is the diameter of the field of view (DFV) of a 1000x objective lens if the DFV of a 400x objective lens is 500 μ? Express your answer in mm.The FOV on low power of a microscope is measured to be 4.5mm. Using the chart below and the above listed formulas calculate: FOvx = FOvlow X Maglow Magx S.S. = FOvx # times the specimen fits across the FOv Total Mag = Ocular lens x objective lens a) What is the FOV on High Power? (Magnification on High power is 40x) Can you please include the units too. asap please.The following image is a scheme for serial dilutions prepared for spectrophotometric analysis. If the stock solution concentration is 0.05 % (v/v) can you calculate the other tube’s concentrations in % v/v? I've used this with direct dilutions, how would I use this on serial dilutions?
- Question 5 What is the total magnification of a sample with an ocular lens power of 15X and using a 40X objective lens?If, when using 10X ocular and a 20X objective, the field size is 2 mm. The approximate field size with a 50X objective is ________ mm. 0.6 0.8 0.4 1Using the scanning (4x) objective and the metric ruler, record the number of millimeters you see along with the letter “e.” Your value: 2 millimeters Convert the figure you attained to micrometers (1 millimeter = 1,000 micrometers). This is the diameter of the field of view for the low-power objective (LPD). The field of view is the circular field you see when you look through the oculars. The field of view changes at different magnifications. Your value (LPD): 2,000 micrometers -please help me with the problem in the picture.
