A fluorescent lamp of length `1m` is placed horizontally at a depth of `1.2 m` below a ceiling . `A` plane mirror of length `0.6 m` is placed below the lamp parallel to and symmetric to the lamp at a distance `2.4 m` from it as shown in figure. Find the length in meters (distance between the extreme points of the visible region along `x`-axis ) of the reflected patch of light on the ceiling.
