Principle Ray II. Preliminary on the object side of the lens ray II heads toward the plane of the lens along a line that is parallel to the principle axis of the lens. At the plane of the lens it suddenly adopts a path that takes it directly away from the focal point that is on the same side of the lens as the object. If you outline that ray straight back the trace-back line passes through said focal point.
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
A block of mass 10 kg is attached to the end of a horizontal spring with spring constant k = 1200 Nm-1. The block is assumed to be sitting on a frictionless horizontal surface.
