(b) What is the angular magnification of the telescope?

## Answer to relevant Questions

You are given two objectives and two eyepieces and are instructed to make a telescope with them. The focal lengths of the objectives are 60.0 cm and 40.0 cm, and the focal lengths of the eyepieces are 0.90 cm and 0.80 cm. ...A nearsighted person has an uncorrected far point of 200 cm. Which type of contact lenses would correct this condition, and of what focal length should it be? A refracting telescope with a lens whose diameter is 30.0 cm is used to view a binary star system that emits light in the visible region. (a) What is the minimum angular separation of the two stars for them to be barely ...Two astronomical telescopes have the characteristics shown in the following table: If a proton has a kinetic energy of 2 MeV, could the classical expression for kinetic energy be used to compute its speed accurately? What if its kinetic energy is 2000 MeV? Explain.Post your question
