If a microscope has an ocular with a 5x power and has objectives with powers of 10x and 50x what is the total magnification of a: low power? high power? show math for full credit!

The correct answer will be-

1. low power magnification- 50X

2. High power magnification- 250X

Explanation:

Magnification of a microscope is the ability of the instrument to magnify the objects.  The magnification of a microscope can be calculated by multiplying the power of the objective lens with an ocular or eyepiece lens.

Magnification= Objective lens power x Eyepiece lens power

In the given question,  

1. Low magnifying power will be- 50X

 Since the objective lens is of 10X and the ocular lens is of 5x

  Therefore, Magnification- 10X x 5X= 50X

2. High magnifying power will be- 250X

Since the objective lens is of 50x and ocular lens is of 5x

Therefore, Magnification=  50X x 5X= 250X

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
