Question

Which of the following is not a type of telescopes?

• A. Reflecting
• B. Refractive
• C. Radio
• D. Scattering

Answer 1

The correct option is D Scattering

Types of telescopes are as listed below:
1. Refracting telescopes:
These deploy a set of two lenses to form images using the principle of refraction.
2. Reflecting telescopes:
These deploy a set of mirrors to form images using the principle of reflection.
3. Radio telescopes:
These deploy a combination of parabolic reflectors and radio receivers. The received information at the radio receiver is then analyzed by computers.
4. Telecopes in space:
These telescopes are placed in satellite orbits above the earth to analyze information from the space. This information is then transmitted to the base stations on the earth.
