Question
Give reason: Electric vector is called light vector.
✓

Answer

As the electric field vector $\left(\overrightarrow{E_0}\right)$ is more prominent than the magnetic field vector $\left(\overrightarrow{B_0}\right)$, it is responsible for optical effects due to EM waves. For this reason, electric vector is called light vector.
