The intensity of X-rays decreases expon...

The intensity of X-rays decreases exponentially according to the law `I=I_(0)e^(-mux)` , where `I^(0)` is the initial intensity of X-rays and I is the intensity after it penetrates a distance x through lead. If `mu` be the absorption coefficient, then find the dimensional formula for `mu` .

Text Solution

Verified by Experts

The correct Answer is:
`L^(-1)`
`[mux]=M^(0)L^(0)T^(0)`
`[mu][x]=M^(0)L^(0)T^(0)`
`[mu] =(1)/(L)=L^(-1)`
