In order to find the diameter of a lens in a German physics task, you will need to use the formula: d = 2f tan(θ), where d is the diameter of the lens, f is the focal length, and θ is the angle of the lens. You will need to know the focal length and angle of the lens in order to calculate the diameter.

There are a few different methods for finding the angle of a lens, depending on the type of lens and the information given in the task. One method is to use a protractor to measure the angle directly. Another method is to use trigonometric functions and the known dimensions of the lens to calculate the angle. It is important to carefully read and understand the given information in order to determine the most appropriate method for finding the angle of the lens.

Yes, you can use any unit of measurement as long as you are consistent throughout your calculations. However, it is recommended to use units such as millimeters or centimeters for better accuracy and precision.
