Which of the following can not be polarised

By Huygens wave theory of light, we cannot explain the phenomenon of

In Young's double slit experiment the spacing between two slits is $$0.1\ mm$$. If the screen is kept at a distance of $$1.0\ m$$ from the  from the slits and the wavelength of light is $$5000\ \overset {o}{A}$$, then the fringe width is

The resolving limit of healthy eye is about 

Wave which cannot travel in vacuum is 

Which of the following statement is wrong

which one of the following phenomenon is not explained by Huygen's construction of wavefront

In Young's double slit experiment if $$L$$ is the distance between the slits and the screen upon which interference pattern is observed $$x$$ is the average distance between the adjacent fringes and $$d$$ being the slit separation. The wavelength of light is given by
