1.

Diameter of lens of telescope is 0.16 m. Wavelength of light is 7500Å, so resolving power of telescope will be ..

Answer»

`1.73xx10^(5)`
`6.67xx10^(6)`
`6.67xx10^(2)`
`6.67xx10^(4)`

SOLUTION :Resolution power of telescope
`=(D)/(1.22 LAMBDA)`
`=(0.61)/(1.22xx75xx10^(-8))`
`=0.00666xx10^(8)`
`=6.67xx10^(5)`
