QNEET-2020-Ph-711: NEET 2020 Physics - Class 12 NEET-2020-Ph-711 Solution: Assume that light of wavelength 600 nm is coming from a star.…

Assume that light of wavelength 600 nm is coming from a star. The limit of resolution of telescope whose objective has a diameter of 2 m is: 1.83×10−7 rad1.83 \times 10^{-7}\ \text{rad} 7.32×10−7 rad7.32 \times 10^{-7}\ \text{rad} 6.00×10−7 rad6.00 \times 10^{-7}\ \text{rad} 3.66×10−7 rad3.66 \times 10^{-7}\ \text{rad}

Multiple Choice Options

  • A 1.83 ×\times _ 10 -7 rad
  • B 7.32 ×\times _ 10 -7 rad
  • C 6.00 ×\times _ 10 -7 rad
  • D 3.66 ×\times _ 10 -7 rad

Step-by-Step Verified Solution

Limit of Resolution for a Telescope is _ = 1.22 _ d Given, _ = 600 _ 10 -9 ; d = 2 m By substituting the values, we get _ = 3.66 _ 10 -7 rad
