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.
