The Yerkes refracting telescope has a 1.00 m diameter objective lens of focal length 20.0 m. Assume it is used with an eyepiece of focal length 2.50 cm. (a) Determine the angular magnification of the planet Mars through this telescope. (b) Are the Martian polar ice caps right side up or upside down

Respuesta :

Answer:

Explanation:

The angular magnification of this telescope = - f₀ / fe = 20 / 0.025 = - 800

where f₀ = 20.0 m, focal length of the objective lens and fe = focal length of the eyepiece

b) since M ( angular magnification ) < 0 , then the martian polar ice cap is upside down
