(a)For a telescope, what is the separation between the objective lens and the eyepiece? (b) If this telescope is used to view a 100 m tall tower 3 km away, what is the height of the image of the tower formed by the objective lens? (c)What is the height of the final image of the tower if it is formed at 25 cm?
Distance of tower is 3000m;h1=100m angle subtended by tower at telescope is θ1=h1/u=1/30 rad angle subtended by image, θ2=h2/fo=h2/140rad as two angles are equal, h2=4.7cm
