Answer:
1.Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. ... Therefore, our eye and brain track the light rays backward to a position from which they appear to have come.
2.To see reflection ,we need a surface which is smooth and reflecting .The more it reflects and the more is it’s smoothness,the more it will give a clear reflection or image .
2.To see reflection ,we need a surface which is smooth and reflecting .The more it reflects and the more is it’s smoothness,the more it will give a clear reflection or image .Mirror is made up of glass which is smooth and have a silver coating behind it so it reflects nearly 99% of light .So we get a clear image in mirror .

3.The phases of the incident, refracted, and reflected light have to be equal at the boundary. You take into account the index of refraction and set up the equation
3.The phases of the incident, refracted, and reflected light have to be equal at the boundary. You take into account the index of refraction and set up the equation(k⋅x)z=0=(k′⋅x)z=0=(k′′⋅x)z=0
3.The phases of the incident, refracted, and reflected light have to be equal at the boundary. You take into account the index of refraction and set up the equation(k⋅x)z=0=(k′⋅x)z=0=(k′′⋅x)z=0 Where k,k′,k′′ are the wave vectors for the incident wave, the refracted wave, and the reflected wave. z=0 is the boundary between the media. x is the position vector.

Hope this will help.
