Students have asked these similar questions
Suppose a 151 mm focal length telephoto lens is being used to photograph mountains 10 km away.
a. Where is the image in meters?
b. What is the height of the image in centimeters of a 2530 m high cliff on one of the mountains? (Include the sign of the value in your answer.)
Draw a labelled ray diagram of a refracting telescope. Show tge images formed by the two lenses
I have already gotten the answers to all of the questions. All I need is the ANGLE for questions 2, 3, and 4.
Please and Thank you. If you can please explain how you got the angle.
