Physics · Refraction of light through a prism, microscope and astronomical telescope (reflecting and refracting) and their magnifying powers
Large astronomical telescopes always use as objective
Large astronomical telescopes always use as objective
- A. Iens
- B. mirror
- C. combinations of lenses
- D. none of the above
Step-by-step solution
Large astronomical telescopes use mirrors as objectives because mirrors can be constructed with large diameters without chromatic aberration, and they are easier to support than large lenses.
