1.

If the wavelength of light used is 6000 Å. The angular resolution of telescope of objective lens having diameter 10 cm is ...... Rad

Answer»

`6.10xx10^(-6)`
`7.32xx10^(-6)`
`6.55xx10^(-6)`
`7.52xx10^(-6)`

SOLUTION :Angular resolving POWER of telescope
`alpha_(min)=(1.22 LAMBDA)/(D)`
`=(1.22xx10^(-5)xx6)/(10)`
`=7.32xx10^(-6)`
