Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
How do you calculate the magnification of a microscope?
To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. The highest total magnification for a compound light microscope is 1000x.
How do you calculate the magnification of binoculars?
Calculate binocular power or magnification by dividing the focal length of the binocular tube by the focal length of the eyepiece. So a binocular tube focal length of 150 mm and an eyepiece focal length of 15 mm would provide a power or magnification of 10 times normal.
How do you calculate magnification in Igcse?
Magnification equation
Magnification = image size / actual size. Actual size = image size / magnification.
How far can 10X50 binoculars see?

HOW FAR CAN military binoculars see?
Some PEO—Soldier representatives characterize the M25 extremely high resolution capabilities as being able to see a golf ball a mile away. Others quantify the capabilities, crediting the system with a maximum range of 4,000 meters with an effective range of 2,500 meters.
Are 20×50 binoculars better than 10×50?
The first number is the magnification so 10 times compared to 20 times, so 20×50 is stronger.
Can you see Saturn with binoculars?
Although a small telescope is needed to see Saturn’s rings, you can use your binoculars to see Saturn’s beautiful golden color. Experienced observers sometimes glimpse Saturn’s largest moon Titan with binoculars. Also, good-quality high-powered binoculars – mounted on a tripod – will show you that Saturn is not round.
What does 10X40 mean on binoculars?
This number refers to how bright an image will appear in low-light conditions. The bigger the number, the brighter the image. It is measured in millimetres and is calculated by dividing the lens diameter by the magnification – a 10X40 pair of binoculars has an exit pupil size of 4mm (40 divided by 10 is 4).
What is the strongest lens in binoculars?
What is the highest power binoculars you can buy? The world’s highest power binoculars are the Oberwerk BT-100XL-SD 100mm binocular telescope with up to 80x magnification.
What are 20×50 binoculars?
