When it comes to scalar multiplication of an identity matrix, you're essentially multiplying every element within this matrix by a scalar, which is simply a real number. Given that an identity matrix is characterized by the presence of 1's on its diagonal and 0's everywhere else, this operation will yield a diagonal matrix where the diagonal is populated by the scalar value.
