RESOLVING POWER OF TELESCOPE
Aim:To determine resolving power of Telescope.
Apparatus Required:Telescope with rectangular variable slit, a scale with black lines of equal width which
measure in millimeter and meter scale.
Formula used:Theoretical value of R.P. of Telescope = a/1.22λ
Practical value of R.P. of Telescope
= mean wavelength of light used.
a = width of variable slit at the time of resolution of two object.
d = distance between two black lines on the scale.
D = distance between object and objective of the telescope.
