Does the photo in a 75-300 lens make the picture look like at 75 feet as it does at 300 feet?
No. My guess is that you have a zoom lens, whose focal length can be varied over the range of
75 to 300 millimeters.
The larger the focal length of the lens, the larger (closer) the objects in the picture appear.
The handy, easy-to-remember rule that I use is: One focal length on the film (or CCD) depicts
one radian in the scene (or sky).
What else can I help you with?
How do you find radius of curvature in achromatic lens if focal length and diameter is given?
You also need to know the index of refraction. For glass, that is usually somewhere around 1.5. The Wikipedia article on "Lens (optics)" includes the "Lensmaker's equation"; usually you can use the "thin lens equation" (further down in the article) as a convenient approximation. Since for this question you don't know the radius of curvature, and the equation includes two radii of curvature (for the two surfaces), I suggest that you make one of the following simplifying assumptions: 1) Either assume that the lens has two surfaces of equal curvature (note: for the equation in the Wikipedia article, the signs would be opposite for both sides), 2) Or, assume that the lens has one flat side and one curved side.
What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x?

How can I take a photo of a framed picture without any reflections?
To take a photo of a framed picture without reflections, position the camera directly in front of the picture, use a polarizing filter on the camera lens to reduce reflections, and adjust the angle of the lighting to minimize glare.
What are the benefits of using photo filters in digital photography?
Photo filters are used to protect the camera lens from scratches but can also cause a distortion of the image as well, causing the picture to be flawed.
What is the difference in the picture of a 35mm lens camera and a 28mm camera?
The 28mm will have a wider view. So you can get more in the photo without taking a step back.
