Try these settings for a start. Create a blinn, in the attribute editor turn transparency all the way up, leave all the common settings at default. Open up the Raytracing options and enable Refractions. Refractive Index 1.3, reflection limit 5 and reflection specularity to around .2.
In the reder globals, enable raytracing, set Reflections, refractions and shadows all to 10. Try a render.
Might not be perfect for your scene but you can fiddle with the settings until it suits your need more.
what i want is that there is a light coming through that window (sunset) does it effect the mirror. do i need to put the mirror cast to shadow so that it will look real in term of lighting
