A beam of light is incident at the polarizing angle of 35^(@) on a certain glass plate. The refractive index of the glass plate is:

A beam of light converges to a point on a screen S. A mirror is placed in front of the screen at a distance of 10cm form the screen. It is found that the beam now converges at a point 20cm in front of the mirror. Find the focal length of the mirror.
