Given : a virus appears to have a diameter of 2mm when observed
through an electron microscope but the actual size of the virus is 10μm,
To Find : the microscope's magnification power
Solution:
the microscope's magnification power * Actual size = Size appear
=> the microscope's magnification power = Size appear / Actual size
Size appear = 2 mm = 2 * 10⁻³ m
Actual size = 10 μm, = 10 * 10⁻⁶ m = 10⁻⁵ m
the microscope's magnification power = 2 * 10⁻³ / 10⁻⁵
=> the microscope's magnification power = 2 * 10⁻³ * 10⁵
=> the microscope's magnification power = 2 * 10²
=> the microscope's magnification power = 200
microscope's magnification power is 200X or 200 times
