According to the Physics Classroom, "When the object is located at the focal point, no image is formed."http://www.physicsclassroom.com/class/refrn/Lesson-5/Converging-Lenses-Object-Image-Relations
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
The focal length of the lens is 10 meters. This can be calculated using the lens formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. Given the object and image distances, we can solve for the focal length.
A 5-50mm lens is a zoom lens with a focal length range of 5mm to 50mm. It allows you to adjust the focal length within that range, giving you the flexibility to capture a variety of shots from wide-angle to telephoto. This type of lens is versatile and can be used for different types of photography such as landscapes, portraits, and street photography.

The focal ratio ( 'f' number ) is the ratio of focal length to diameter. For the numbers given in the question, assuming they're both in the same unit, this telescope is a 25/5 = f/5.

5cm and 50mm are the same thing.
The closer the object is to the camera, the shorter the "focal distance". The depth of field gets shallower as the focal length decreases, up until the lens has reached its minimum focusing distance (closer than that and the image will be blurry). If you photograph something at F1.8 that is 5 feet away, your depth of field (area in focus) might be 3 feet (1.5 feet each side of focal point), where if you took a shot at F1.8 but 30 feet away from your subject, the depth of field could be 20 feet (10 feet each side of focal point). I've made up these numbers, but there are charts you can use to calculate DoF based on focal length and aperture.
1. - It is refracted (bent) relative to the source. 2. - The spectrum is separated, the amount depending on the thickness and curvature. 3. - A small part of the light is reflected off the lens, not passing through it. 4. - Assuming a 'perfect' regular (convex) lens, all light passing through the lens focuses at a single point in space, (focal point). 5. - Any image passing through the lens is reversed, equidistant from the focal point.
