Morphology
The meaning is directly compositional: 'refracting' (bending/altering the direction of light) combined with 'telescope' (device for viewing distant objects) yields a telescope that forms images by refracting light through lenses. This is a straightforward descriptive noun phrase following common compounding patterns and is therefore understandable to a B1 learner who knows the constituent words.
Etymology
Refracting telescope comes from the verb refract meaning 'to bend' and the word telescope meaning 'a tool for looking far away'. It uses a large glass lens that bends light to make a clear image, so the name reminds us it makes pictures by bending light.
