This is a big one for social workers, because many of us work in crisis situations. Employers want to make sure you can handle stressful situations and take the time for self-care. They donât want to hire someone who will burn out quickly.
This is what makes the image look smaller. The biggest refracting telescope in the world is located at the Yerkes Observatory of the University of Chicago at Williams Bay, Wisconsin. It has an objective lens thats 1.02 meters (40 inches) across, and its total power is 195x. Reflecting telescopes, on the other hand, dont use lenses at all.
If the focal ratio of your telescope is not printed on the telescope, you can determine it by dividing the focal length by the aperture. If you have a 762mm focal length and an aperture of 6 (152.4mm) then 762 / 152.4 = 5 or f/5 focal ratio. telescope's ability to gather light is dependent on: Aperture ... the larger the primary optics (the largest lens or mirror) the more light is captured. Optical quality ... the more reflective a mirror and the more a lens allows light to pass through it, the more light is transmitted to your eye.
