Physics · Refraction of light through a prism, microscope and astronomical telescope (reflecting and refracting) and their magnifying powers
A reflecting telescope utilises:
A reflecting telescope utilises:
- A. a convex mirror
- B. a concave mirror
- C. \) a prism
- D. a plano-concave lens
Step-by-step solution
A reflecting telescope uses a concave mirror as its primary mirror to collect and focus light. Convex mirrors diverge light and are not used in reflecting telescopes. Prisms or plano-concave lenses are not the primary optics in such telescopes; they may be used in other instruments.
