Slide 3: 

3 A Telescope is an instrument designed for the observation of remote objects by the collection of electromagnetic radiation

HISTORY : 

4 HISTORY Refracting telescopes in Netherlands in 1608. Newtonian reflector in 1668. Achromatic lens in 1733. Radio telescope went to operation in 1937.

OPTICAL TELESCOPE : 

5 OPTICAL TELESCOPE Optical telescopes increase the apparent angular size of distant objects.

Types of optical telescopes : 

6 Types of optical telescopes Refracting telescope. Reflecting telescope. Catadioptric telescope. Other optical telescopes Infrared telescopes. Submillimetre telescopes. Ultraviolet telescopes. Fresnel imager.

RADIO TELESCOPE : 

7 RADIO TELESCOPE The very large array at Socorro,New Mexico,US. They are directional radio antennas used for radio astronomy.

HIGH ENERGY PARTICLE TELESCOPE : 

8 HIGH ENERGY PARTICLE TELESCOPE X-ray telescope use wolter telescope composed of ring shaped glancing mirrors made of heavy metals.
