1/22/2024 0 Comments Telescope drawing labeledThis shows that the mirrors are aligned.Īfter the six-month mark, Webb begins its science mission and starts to conduct routine science operations.įind more detail about the telescope’s size, mirrors, sunshield, orbit, and more. In a simple refracting telescope, which has the longer focal length: the objective lens or the eyepiece lens Objective. In the fourth month after launch, Webb completes its first orbit around L2-and takes the first focused image. Engineers and scientists carefully activate and confirm each and every instrument works properly before the first-but still unfocused-image of a star field is delivered about two months after launch. (c) Explain two advantages of a reflecting telescope over a refracting telescope. (b) Obtain the mirror formula and write the expression for the linear magnification. Draw a small rectangular shape and then attach a thin rectangular shape onto it. Then, we will be drawing a small mirror on a hinge, and this would be used as a light source for the microscope. This shape will also have some small circles on it. It is beneficial for launch sites to be located near the equator: The spin of the Earth can help give an additional push to the rocket.Īfter launch and during the first month in space, on its way to the second Langrange point (L2), Webb undergoes a complex unfolding sequence.ĭeploying, tensioning, and separating Webb’s sunshield, a five-layer, diamond-shaped structure the size of a tennis court extending its secondary mirror support structure and unfolding its primary mirror, which has a honeycomb-like pattern of 18 hexagonal, gold-coated mirror segments.ĭeployment and commissioning take time-at least six months. (a) Draw a ray diagram to show image formation when the concave mirror produces a real, inverted and magnified image of the object. First, draw a rounded shape underneath the arm and the stage of the microscope. At the point that the beams of light enter the concave eyepiece, redraw the lines to continue to the right in parallel beams. In 2021, Webb was carefully folded up and loaded onto a ship, which passed through the Panama Canal on its way to French Guiana in South America, where it reached its launch site at the European Spaceport located near Kourou. n Figure 1 (be\ In Figure 1 (below), use your pencil and ruler to trace the beams of light to a focus point, indicated by the point at the right of the sketch, labeled F.
