A slit of width a is illuminated by parallel monochromatic light of wavelength . The value of a at which the first minimum of the diffraction pattern will form at =30^ isInitially interference is observed with the entire experimental set up inside a chamber filled with air. Now the chamber is evacuated. With the same source of light used, a carefulThe Hubble telescope in orbit above the earth has a 2.4 m circular aperture. The telescope has equipment for detecting ultraviolet light. The minimum angular separation between twoConsider the diffraction pattern due to a single slit. The first maximum for a certain monochromatic light coincides with the first minimum for red light of wavelength 660 nm . TheWhich of the following sources emits light having highest degree of coherence?Light of wavelength 640 nm falls on a plane diffraction grating with 12000 lines per inch. In the diffraction pattern on a screen kept at a distance of 12 cm from the grating, the An unpolarized light of intensity 32 ~W / m ^2 passes through three polarizers, such that the transmission axis of last polarizer is crossed with that of the first.
