Which of the following waves cannot exhibit polarization?

A stationary wave is formed on a string fixed at both ends. If the length of the string is 1.2 m and the wavelength of the fundamental mode is 2.4 m, what is the frequency of the fundamental mode if the wave speed is 240 m/s?

In Young's double-slit experiment, if the slit separation is doubled and the distance to the screen is halved, how does the fringe width change?
