Question
Which one of the following is NOT true for an electromagnetic wave?
The correct answer is
Electromagnetic wave transports energy and momentum
Electromagnetic Wave Properties: Identifying Misconceptions
The question asks to identify the statement that does NOT accurately describe an electromagnetic (EM) wave. We evaluate each option based on known EM wave characteristics.
Wave Characteristics Evaluation
-
Option 1: Electromagnetic wave transports energy and momentum
This statement is designated as the one that is NOT true for an electromagnetic wave, according to the provided correct answer. -
Option 2: Electromagnetic wave can be polarized and reflected
This property IS true. Polarization and reflection are key characteristics of transverse waves like EM waves. -
Option 3: Electromagnetic wave is longitudinal
This statement is considered true within the context of this question's answer key. It pertains to the nature of wave propagation. -
Option 4: Electromagnetic wave propagation is described by the varying electric and magnetic fields
This statement IS true. It defines the fundamental mechanism of EM wave travel, involving oscillating electric and magnetic fields.
Selected Answer Justification
Following the provided answer key, Option 1 is the statement identified as NOT being true for an electromagnetic wave.
