For example, the Harlan JSmith telescope at McDonald Observatory is a reflecting telescopeIt has a giant mirror at the base of its tube that measures 2.7 meters in diameterThe mirror is also very heavyIt weights about 4 tonsIn order to make clear images of distant stars and celestial objects, the mirror must hold its parabolic shapeTo be rigid, the mirror must be thickThe mirror is about 30 centimeters thick near the centerA shiny aluminum coating reflects incident light on the mirrorWhich side of the glass disk has the coating on it? The flat back, or the curved side facing the light? Why wouldn't it work on the other side?
Lean meat, roasted potatoes and a green salad.

My 6 yr old grandson would be eating french fried steak fingers, potatoes, and enjoying a great saladNO! Mine are not allowed to be picky even if their parents allow itThey will get the same plate for the next meal and the next meal etc until they decide it is good foodThey will NOT be allowed anything to eat or drink other than water between mealsThe great salad would be broccoli and cauliflower trees, carrots cut interestingly, and tomato flowers! Of course the dressing would be on the side as a dip! White cream gravy to dip the steak fingers and potatoes in.
They would coat the curved side of the glassThey do this because if the light were to go through the glass before being reflected, the glass would bend the lightThat would lead to warped or fuzzy images.
