This equation assumes the angular magnification is 1.xamy said:di/do=hi/ho
I don't have angular magnification or focal length so I can't find the distance.haruspex said:This equation assumes the angular magnification is 1.
You need further information, e.g. the distance from the actual wing to... something. Go to http://en.wikipedia.org/wiki/Magnification#Magnification_as_a_number_.28optical_magnification.29 and search for "25".
Did you find the reference to 25 at the link?xamy said:I don't have angular magnification or focal length so I can't find the distance.
I have solved the question using 25cm for the distance. Thankyou for your guidance. Sorry earlier I was looking at the wrong portion of this link.haruspex said:Did you find the reference to 25 at the link?

Angular magnification is a measure of how much an object appears to be magnified when viewed through a lens or optical instrument. It is important in scientific calculations because it allows for accurate measurements and comparisons of small objects or details that may not be visible to the naked eye.
Angular magnification is calculated by dividing the image distance (distance from lens to image) by the object distance (distance from lens to object).
The accuracy of angular magnification calculations can be affected by several factors, including the quality and design of the lens, the distance between the lens and the object, and any errors or distortions in the optical system.
To minimize errors in angular magnification calculations, it is important to use high-quality lenses and to ensure that the object and image distances are measured accurately. Regular maintenance and calibration of optical instruments can also help reduce errors.
If you encounter an unexpected error in your angular magnification calculation, it is important to double-check your measurements and ensure that all components of the calculation are correct. If the error persists, consult with a colleague or refer to the instrument manual for troubleshooting tips.
