As light travels from vaccum to glass only its speed and wavelength will change, its frequency will remain constant.
An image formed behind a mirror is erect not inverted.
An image formed behind a mirror is always virtual as real images are formed only when rays of light actually meet, and rays of light cannot meet at the back of the mirror.

where c is the speed of light in vaccum , and v is the speed of the light in the particular medium.
Refractive index of a medium should be 1 in order for light to have same speed as in vaccum in that particular medium.
In the above equation v and lamda changes such that frequency is kept constant when light moves from one medium to another.
