Shape Of Interference Fringes In Ydse

The fringes produce in diffraction pattern are of

In a YDSE setup interference fringes are obtained by sodium light of wavelength 5890Å . On screen the fringes have an angular width 0.20^(@) . Now the wavelength of light is changed and it is found that fringe width increases by 10%, the new wavelength of incident light is :

A parallel beam of light travelling in water is incident obliquely on a glass surface. After refraction its width ………………….

No fringes are seen in a single-slit diffraction pattern if
