The James Webb Space Telescope has a primary mirror of diameter ? = 6.5metres. When observing at 1100nm wavelength, calculate the minimum angular separation between two stars which can just be resolved; give your answer in arcseconds (arcsec), where 1 arcsec = 1/3600 degree, to 3 decimal places.
Infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on Earth to study the earliest stages of star formation, before a star begins to emit visible light. Suppose an infrared telescope is tuned to detect infrared radiation with a frequency of 3.30 THz. Calculate the wavelength of the infrared radiation.
Be sure your answer has the correct number of significant digits.
