Define slenderness ratio. What is its effect on the design of compression member?

Slenderness ratio is noting but length to radius of column we have different names with different values of range of its value is <4,it's pedastal column,<12,>4is short column,if it's >12its long or slender column

In concrete, slenderness ratio=(unsupported length/least lateral dimension)
In steel, Slenderness ratio=(effective length/minimum radius of gyration)
Effects: it defines the buckling of column to the different end conditions
