Q1. Which type of telescope uses lenses to bend and focus light? 🔍
- Reflector
- Refractor
- Radio dish
- Catadioptric
Answer: Refractor
Q2. What is the main benefit of using a mirror instead of a lens in a large telescope? 🪞
- Mirrors are always cheaper to manufacture than lenses
- Mirrors allow for a longer light path in a shorter tube
- Mirrors can be made thinner and lighter than lenses of the same size
- Mirrors eliminate the need for a secondary optical element
Answer: Mirrors can be made thinner and lighter than lenses of the same size
Q3. How do X-ray telescopes detect radiation that would normally pass through standard mirrors? ⚡
- By using high-precision silicon detectors to track particles
- By using a grazing incidence mirror design where X-rays skip off the surface
- By using a corrector plate to fold the light path
- By using a calorimeter to absorb and measure energy
Answer: By using a grazing incidence mirror design where X-rays skip off the surface
