Yes it is possible. Spectrum of emitted light depends upon the chemical composition of the source. and the way of its excitation. a clear example to us is that of sun.
Vectors are used to represent physical magnitudes that have an associated address. For example, if we want to represent the displacement of an object, it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred, for example, 30 ° towards the northeast.
Therefore the vectors are measured in one or several dimensions that include a magnitude and an address.
The correct option is the last:
"<em>a measurement in more than one dimension that includes a magnitude and a direction</em>"
