Question

Draw a labeled ray diagram of a reflecting telescope. Mention its two advantages over the refracting telescope.

Solution

Reflecting Telescope,

Its two advantages over Refracting telescope:

1. It reduces the spherical aberration and forms a clear focused image.

2. It doesn’t require a lens of very large aperture as refracting type requires that cannot be manufactured easily.
