Describe what happens to a Fraunhoffer single slit diffraction pattern, if (a) the whole apparatus is immersed in water (b) red light is replaced by blue light?

A diffraction pattern is obtained using a beam of redlight. What happens if the red light is replaced by blue light

A diffraction pattern is obtained using a beam of redlight. What happens if the red light is replaced by blue light

A Young's double slit apparatus has slits separated by 0.25mm and a screen 48cm away from the slits. The whole apparatus is immersed in water and the slits are illuminated by the red light ( lambda=700nm in vacuum.) Find the fringe width of the pattern formed on the screen. (mu_w = 4//3)

In a Fraunhofer diffraction at a single slit, if yellow light illuminating the slit is replaced by blue light, then diffraction bands

A Young's double slit apparatus has slits separated by 0.28 mm and a screen 48 cm away from the slits. The whole apparatus is immersed in water and the slits are illuminated by the red light ( lamda=700 nm in vacuum). Find the fringe-width of the pattern formed on the screen.

In young's double slit experiment the slits are illumated by light of wavelength 5890^(@) A and the angular distance between the fringes obtained on the screen is 0.2^(@) . If the whole apparatus is immersed in water then the angular fringe width will be, if the refractive index of water is 4//3

In a Young's double slit experiment, the fringe width is found to be 0.4mm . If the whole apparatus is immersed in water of refractive index 4//3 without disturbing the geometrical arrangement, the new fringe width will be

In a Young's double slit experiment, the fringe width is found to be 0.4mm . If the whole apparatus is immersed in water of refractive index 4//3 without disturbing the geometrical arrangement, the new fringe width will be

In a single slit diffraction pattern, if the light source is used of less wave length then previous one. Then width of the central fringe will be-

If I_0 is the intensity of the principal maximum in the single slit diffraction pattern. Then what will be its intensity when the slit width is doubled?
