0 Preflight 4
The image is formed an equal distance BEHIND the mirror
Therefore, if you stand a distance = ½ of your near point, the distance to the image will be the near point distance. d Preflight 6
3. Parallel rays are transmitted and pass through focal point (f1)
Those rays also pass through focal point of second lens (f2) and therefore are transmitted parallel to the axis.
f2 > f1 implies that the width > w1 25

Currently being built in Chile.
Various members of our Phys
Dept are part of the scientific
team. Operational in 2015. Particular scientific goals of the LSST include:
•Measuring weak gravitational lensing to detect signatures of dark energy
and dark matter in the universe.
•Mapping near-Earth asteroids
•Detecting Novae and supernovae
•Mapping the Milky Way How to ma...
