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).

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 is the root words in telephoto lens?
Photo meaning light.Tele meaning sound. Lens isn't a root word I'm just going to tell you that.
When you take a photo you always see these bright circles over peoples heads what ar they are they spirits?
99.9% of the time they are dust. The relationship of the flash to the camera lens causes a reflection that gets captured when the picture is taken. By moving the flash farther away from the lens, you can virtually eliminate this issue.
Is quality of photo affected because of ISO?
Yes, if the ISO is raised too high it will cause the pictures to be grainy. Too much ISO allows for too much light into the lens causing the picture to be noisy.
What things can you do to the pictures on the Nintendo DSi?
The Nintendo DSi camera has 11 different features. 1. Normal lens takes normal photos. 2. Distortion lens you can distort photos (make them look funny) 3. Graffiti lens you draw on photos. 4. The mirror lens makes a kinda symmetry picture and other things 5. Mischief lens you can put glasses and mustaches on ppl 6. Emoter lens you can change ppls expressions 7. The Merge lens you merge two faces together 8. Resemblance lens is where u take a picture of 2 ppl n c how much they r related 9. Frame lens put frames around the picture Also there are two different lens where you can change the colour of a picture or take a black and white picture. sorry for the long explanation...
