The angular resolution of a 30 meter diameter radio telescope observing a radio signal of 21 centimeters would be X arcseconds,while the angular resolution of the fully dilated human eye,with diameter of about 5 mm, gathering light at an average of 6x10^(-7) meters in wavelength would be Y?
because, angular resolution is given as:
R = 1.22*lambda/D radian
For X: lambda = 21 cm (HI ...
The angular resolution of a wavelength is found. The light at an average is determined.
