Explain why. a) A wider aperture can observe a significantly larger portion of the sky. b) A wider aperture makes a telescope easier to aim. c) A wider aperture allows a telescope to collect more light, so it can produce images with higher resolution. d) A wider aperture allows a telescope to collect more light, so it can detect fainter light sources.arrow_forward
