Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Radio telescopes are telescopes used for the detection of radio emission from space. Because radio waves have much longer wavelengths than visible light, the diameter of a radio telescope must be very large to provide good resolution. For example, the radio telescope in Penticton, BC in Canada, has a diameter of 26 m and can be operated at frequencies as high as 6.6 GHz. (a) What is the wavelength corresponding to this frequency? (b) What is the angular separation of two radio sources that can be resolved by this telescope? (c) Compare the telescope’s resolution with the angular size of the moon.

The phase shift between ordinary and extraordinary waves in the plastic and thus the degree of transmission is dependent on both the birefringence An (= no-ne), and the air wavelength 20: Ap= (nod-ned) (2π/20) where the symbols have their usual meaning. If we have a situation whereby, at a particular region in the plastic, for blue light (20= 450nm) the phase shift is 47 and the blue light is not transmitted, at what wavelength will the phase shift be 3r, where the transmission will be a maximum? What will happen to the blue light if we rotate one of the polarisers so that the transmission axes of the two are now parallel?
