Consider matrices in R 3×5 . What is the maximum possible number of linearly independent column vectors?

if a matrix 3 x 5 it does not imply that the column vector are linearly independent.

Explanation:

A 3 x 5 matrix represents a linear map . we have 5 columns vectors of . they can never be linearly independent because the dimension of is 3.

wavelength variability is the right one

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
