WebIf the Hubble Space Telescope pointed to Earth, what resolution would the images have? Hubble's so-called angular resolution — or sharpness — is measured as the smallest angle on the sky that it can resolve (i.e. see sharply). This is 1/10 of an arcsecond (one degree is 3600 arcseconds). WebUnder the Rayleigh criterion, the smallest angular separationθ that two point sources can have and stillberesolvableas twoindividualpointsources is θ =1.22 λ D (2) where θ is the angular resolution in radians,λ is the wavelength of the light, andD is the diameter of the aperture of the instrument. For the Hubble Space Telescope, WebThe angular resolution in degrees is approximately Δ θ ≈ 60λ/L, where λ is the wavelength and L is the aperture length. Since acoustic wavelengths are large when compared with optical wavelengths, the angular resolutions tend to be large especially at low frequencies (Sonars with angular resolutions of 1° are generally considered to have high resolution. bobs calvin couch
