The disntances of poinnt on the screen from two slits are 1.8xx10^(-5)m and 1.23xx10^(-5)m . If the wavelength of light used is 6000 Å, then the number of bright or dark band formed at that point is

In fresnel's biprism experiment the distance between the source and the screen is 1 ma nd that between the screen is 1 m and that between the source and biprism is 10 cm. the wavelength of light used is 6000Å. The fringe width obtained is 0.03 cm and the refracting angle of biprism is 1^(@) then calculate the refractive index of the material of biprism.

In YDSE, the distance between the slits is 1 m m and screen is 25cm away from the slits . If the wavelength of light is 6000 Å , the fringe width on the secreen is

In the Young's double slit experiment, the spacing between two slits is 0.1mm . If the screen is kept at a distance of 1.0m from the slits and the wavelength of ligth is 5000Å , then the fringe width is

In a biprism experiment, the distance between the sit and the eyepiece is 1m and distance between the two coherent sources is 0.5 mm. If the wavelength of light used I 6000Å , then distance of the 10th bright and from the central bright band is

In a double experiment, the distance between the slit is 1 mm and screen is 25 cm away from the slits. The wavelength of light is 6000Å . The width of the fringe on the screen is

In YDSE with monochromatic light, fringes are obtained on the screen placed at some distance from the slits. If screen is moved by 5 xx 10^(–2)m towards the slits, fringe width changes by 3 xx 10^(-5) m . If separation between the slits is 10–3 m, if wavelength of light used is 1000 y Å, then y is : (Assume distance between the two slits is very small than the distance betwen the slits and screen)

In young's double-slit experiment , the spacing between the slits is 'd' and the wavelength of light used is 6000Å If the angular width of a fringe formed on a distance screen is 1^@ then calculate 'd' .
