The study of biomechanics ranges from the inner workings of a cell to the movement and development of limbs, to the mechanical properties of soft tissue, and bones.
Radio telescope. A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects.
Differences between Optical and Radio Astronomy. There are many differences between optical and radio astronomy. The three main differences are the design of the instruments, the resulting data that is found, and the different sources that are seen. Both optical and radio astronomy use telescopes; however, there is a big difference in the design between an optical telescope and a radio telescope. Optical astronomy is the study of the visible part of the electromagnetic spectrum, that is wavelengths of approximately 400 nm (purple) to 700 nm (red). Radio wavelengths are much longer; the radio spectrum ranges from approximately one millimeter to hundreds of meters.
