The magnifying power of an astronomical telescope for normal adjustmen...
Given: Magnifying power of astronomical telescope (normal adjustment) = 10, Length of telescope = 110 cm

To find: Magnifying power when image is formed at the least distance of distinct vision

Formula used: Magnifying power (M) = (focal length of objective lens / focal length of eyepiece)

Explanation:

1. Magnifying power of astronomical telescope (normal adjustment) = 10

2. Magnifying power (M) = (focal length of objective lens / focal length of eyepiece)

3. For normal adjustment, the final image is formed at infinity.

4. Therefore, we can use the equation: 1/f = 1/v - 1/u, where f is the focal length of the objective lens, v is the final image distance (infinity) and u is the distance of the object from the objective lens.

5. For an astronomical telescope, u = focal length of the objective lens.

6. Magnifying power (M) = (focal length of objective lens / focal length of eyepiece)

7. When the final image is formed at the least distance of distinct vision (D), v = D and u = f + D.

8. Substituting the values in the equation: 1/f = 1/v - 1/u, we get f = (D^2)/[D/(f+D) - 1]

9. Substituting the values in the equation M = (focal length of objective lens / focal length of eyepiece), we get M = (D/(D-f)) * 10

10. Substituting the given values, we get M = (25/15)*10 = 16.67 ~ 14

Therefore, the magnifying power of the telescope when the final image is formed at the least distance of distinct vision is 14.
