AI Generated Solution

### Step-by-Step Solution: 1. **Identify the Question**: The question asks for two advantages of a reflecting telescope over a refracting telescope. 2. **Advantage 1 - Brightness of Image**: - In a reflecting telescope, there is no loss of intensity of the incident light. This is because the telescope uses mirrors, which reflect light rather than refract it. - In contrast, a refracting telescope uses lenses, and during the process of refraction, some light is lost due to absorption and scattering. - As a result, reflecting telescopes provide a brighter image compared to refracting telescopes. ...
