Objective focal length (fo) = 2 cm
Eyepiece focal length (fe) = 4 cm
Tube length (L) = 40 cm
Distance of distinct vision of eye (D) = 25 cm
Formula for magnification (m) of the microscope:
m = (L / fo) × (D / fe)
⇒ m = (40 / 2) × (25 / 4)
⇒ m = 125
Final Answer: The magnification in the microscope is 125.
