It can easily be appreciated that a combination of three mutually perpendicular mirrors would reflect a light-ray incident from any direction through . Such a combination of mirrors is called a corner-cube reflector. Astronauts on the Apollo 11 mission (1969) left a panel of corner-cube reflectors on the surface of the Moon. These reflectors have been used ever since to measure the Earth-Moon distance via laser range finding (basically, a laser beam is fired from the Earth, reflects off the corner-cube reflectors on the Moon, and then returns to the Earth. The time of travel of the beam can easily be converted into the Earth-Moon distance). The Earth-Moon distance can be measured to within an accuracy of using this method.

The microscope magnification depends on both ocular lens and objective lens magnifications. Microscope maginification = Ocular lens magnification × Objective lens magnification You can measure the microscopic field of view on a lower power. Then the field of view of higher power can be calculated based on following formula: Low power magnification × Low Power field of view = high power magnification × high power field of view Microscope magnification calculation examples: When the ocular lens is 10× and the objective lens is 10×, the field of view is 800 µm. How to calculate the filed of view when the ocular lens is 40× and the objective lens is 100×? Solution: The magnification at lower power is 10 × 10 = 100 The magnification at higher power is 40 × 100 = 4000 higher power field of view = 100 × 800 / 4000 = 20 µm

It either diverges from or converges to this beam waist. This divergence or convergence is measured by the angle θ which is subtended by the points on either.
