How to Calculate Magnification on a Light Microscope
Updated April 30, 2018
By Karen G Blaettler
Microscopes magnify the tiniest inhabitants of this world. From the minute details of cells to the delicate cilia of paramecium to the intricate workings of Daphnia, microscopes reveal many miniscule secrets. Calculating total magnification uses simple observation and basic multiplication.
Basic Microscope Design
Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.
Compound microscopes use two or more lenses to magnify the specimen. The standard school microscope combines two lenses, the ocular and one objective lens, to magnify the object. The ocular or eyepiece is found at the top of the body tube. The objective lens points down toward the object to be magnified. Most microscopes have three or four objective lenses mounted on a rotating nosepiece. Rotating the nosepiece lets the viewer change the magnification. Different objective lenses provide different magnification options.

Finding Lens Magnification
Finding the magnification of each lens requires examining the casing of each lens. On the side of the casing is a series of numbers that includes a number followed by x, as 10x. This 10x shows that the lens magnifies an object to appear ten times larger than reality. Depending on the manufacturer, this magnification number may appear at the beginning or at the end of the number sequence. To calculate total magnification, find the magnification of both the eyepiece and the objective lenses. The common ocular magnifies ten times, marked as 10x. The standard objective lenses magnify 4x, 10x and 40x. If the microscope has a fourth objective lens, the magnification will most likely be 100x.
Calculating Magnification
Once the magnification of each individual lens is known, calculating total magnification is simple math. Multiply the magnification of the lenses together. For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is 10 × 4 = 40. The total magnification of 40 means that the object appears forty times larger than the actual object. If the viewer changes to the 10x objective lens, the total magnification will be the ocular's 10x magnification multiplied by the new objective lens's 10x magnification, calculated as 10 × 10, for a total magnification of 100x.

The answer is "Option C".
Explanation:
The Mediterranean Sea has always been the core of modern culture throughout the decades. It is a region rich in history, which has been key in shaping shipping and trading, as a tool for supplying growing populations, and also as a way of spreading but intermarrying countries and ethnicities. For example, it was usually referred to as Muscovy (Latin, Our Ocean) and sometimes by the Romans as Mare Internum.

Answer: It takes about 500 seconds for light to reach earth from the Sun which is also 8minutes 20 seconds
Explanation: The earth orbits around the sun at a distance of 150 million kilometres. Sunlight travels at the speed of light which is 300,000 kilometres per second.
Firstly, convert 300 million metres to kilometre; 1000 metres = 1 kilometre
Therefore, 300,000,000 metres= 300,000,000/1000= 300,000 kilometers. This gives us the speed of light which is 300,000 kilometers per second
To get the time it takes for sunlight to get to the earth, divide 150,000,000 by 300,000.
Since Time = distance/speed.
150,000,000/300,000= 500seconds
Answer:
Latitude and Longitude have been used as a grid measurement system for navigating the earth for hundreds of years.
Explanation:
One of the main and best known terrestrial location systems is the geographic coordinate system, which arises from the combination of latitudes and longitudes. Thus, these two elements together indicate the exact reference of any point on our planet's surface relative to its whole, allowing both absolute location and relative distance between two locations.
Latitude is the distance, in degrees, from any point on the earth's surface to the Equator Line, the main land parallels. The parallels, in turn, are the imaginary lines drawn horizontally to the earth's main axis, east-west or west-east.
Thus, the Equator Line, which is in the exact position of equal distance to the two terrestrial poles, has a latitude of 0º, increasing north to 90º and decreasing south to –90º.
Longitude, in turn, is the distance in degrees from any point on the earth's surface to the Greenwich Meridian, an imaginary line that, by convention, separates the western and eastern hemispheres. Meridians are lines drawn vertically north-south or south-north.
