Which of the following statements about light in a vacuum is incorrect?
A)Light always travels with the same speed c regardless of the motion of the source or observer.
B)light has wavelike properties
C)light has particlelike properties
D)Light is an electromagnetic wave with its electric-field vector pointing parallel to the direction of propagation.
E)light can be plane polarized

Question

Quizplus · Accepted Answer
