Measure the distance from the center of the lens to the area where it 1.)Produces a clear image of very distant objects, 2.) The Sun (Be careful!), 3.) The Moon, 4.) A bright star or planet. The source needs to be at or near infinity. If you use a light source that is close to the lens, your results will not be accurate. Of course, if you know the F ratio, you have it! An F/2 lens will be twice the diameter of the lens. An F/10 will be ten times, etc.

Why cant opaque objects be veiwed under a compound microscope?

That is certainly not true. A "compound" microscope is one that has an objective AND an ocular. Typically the front focal distance is so short that illumination through the specimen is most common. A "simple" microscope has only one magnifying lens group, not two or more. Short front focus makes lighting from the side more difficult but not impossible or even rare.

What are the main differences between a 35mm and a 55mm lens in terms of focal length and how do these differences impact photography?

A 35mm lens has a shorter focal length than a 55mm lens, which means it captures a wider field of view. This makes it ideal for landscapes and group shots. On the other hand, a 55mm lens has a longer focal length, allowing for closer shots and better compression of the background. This makes it great for portraits and capturing details. The choice between the two lenses depends on the desired composition and style of the photograph.


What are the main differences between the 18-55mm and 55-200mm lenses in terms of focal length and versatility for photography?

The main difference between an 18-55mm and a 55-200mm lens is their focal length range. The 18-55mm lens is more versatile for everyday photography, offering a wider angle for capturing landscapes and group shots. On the other hand, the 55-200mm lens is better suited for capturing distant subjects with its longer zoom range, making it ideal for sports or wildlife photography.
