The correct statement among the following

1.	The correct statement among the following
Answer» A node is a POINT in space where the wave-funtion Y has zero AMPLITUDE . The number of maximum (peaks) in radial probability distribution function is (n-l) Radial probability density is `4PI r^2 R_(n.l)^2 (r)` `PSI`represents probability of FINDING electron Solution :At node `Psi^2 = 0 ` number of radial nodes = n-l-1 nodes of peaks = n-1
