What is the angular radius θ1θ1theta_1 of the first dark ring for a point source being imaged by this telescope? Use 550550 nanometers for the wavelength, since this is near the average for visible light.

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10
