In YDSE performed with wavelength `lambda = 5890 Å` the angular fringe width is `0.40^(@)`. What is the angular fringe width if the entire set-up is immersed in water?

A double slit arrangement produces interference fringes for sodium light (lambda = 5890 Å) that are 0.40^(@) apart. What is the angular fringe separation if the entire arrangement is immersed in water?

A young's doubel slit arrangement produces interference fringes for sodium light (lamda=5890Å) that are 0.20^(@) apart. What is the angular fringe separation(in degree) if the entire arrangement is is immersed in water? (refractive index of water is 4/3).

A double-slit arrangement produces interference fringes for sodium light ( lambda= 589 nm ) that are 0.20^@ apart. What is the angular fringe separation, if the entire arrangement is immersed in water. (n = 1.33)

In YDSE wavelength of light used is 500 nm and slit width is 0.05 mm . then the angular fringe width will be.

In YDSE wavelength of light used is 500 nm and slit width is 0.05 mm . then the angular fringe width will be.

In a double-slit experiment the angular width of a fringe is found to be 0.2^@ on a screen placed 1 m away. The wavelength of light used is 600 nm. What will be the angular width of the fringe if the entire apparatus is immersed in water? Take refractive indexof water to be 4/3 .
