In Fresnel’s biprism experiment if the screen is moved away from the biprism, then the fringe width will :

In the Fresnels biprism experiment, the two coherrent sources are obtained by :

Light of wavelength 5000 Å, illuminates the slit in a biprism experiment. If it is replaced by light of wavelength 6500 Å, then the fringe width will

In Fresnel's biprism experiment, on increasing the prism angle, the fringe width will

In Fresnel’s biprism, coherent sources are obtained by :

In the biprism experiment keeping the experimental set up unchanged, the fringe width

In a biprism experiment , fringe width is measured as 0.4 mm . When the eyepiece is moved away from the biprism through 30 cm, the fringe width increase by 50% if the two virtual soruces are 0.6 mm apart, find the wavelength of light used.

In a Fresnel's biprism experiment, sodium light of wavelength 5832 Å is used. Calculated the fringe width, given the distance between the screen and the biprism =120 cm and the distance the two sources=0.04 cm.

In Fresnel’s biprism experiment, which of the following light sources used to locate central fringe :
