KB’s Reflection is the measure of distance travelled (say by light) in a rectangle starting from any one corner and reaching any another corner in the rectangle moving by reflection whenever a side of rectangle is reached.
We take a rectangle and divide rectangle into squares. The light is assumed to enter in such a way that the light entering in a square from one corner will leave the square from opposite corner.
There are two modes:
Normal Mode The light reflects when it reaches side of the square.
Block Mode Here we move block by block in the diagonal direction.
Example: Let rectangle be of say X units (length) and Y units (breadth) or we can say that there are X columns and Y rows i.e X*Y no. of Squares. Let there be 3 rows and 5 columns.
