Question

Electromagnetic wave is deflected by
A. Electric field
B. Magnetic field
C. Both (1) and (2)
D. Neither electric field nor magnetic field

Answer 1

Hint: This question is theory-based and can easily be answered by understanding the basic properties of electromagnetic waves such as electromagnetic waves are formed by magnetic and electric fields.

Complete Step-by-Step solution:
EM waves are formed by electric and magnetic fields but are not deflected by them, and also they can be deflected by gravitational fields. Light (electromagnetic wave) has an electric and a magnetic field and should thus deflect a compass needle during daytime. Visible light - Being an Electromagnetic wave is reflected by glass (take mirror). For highly intense X-Rays & gamma rays, assume that the mirror is stronger such that it could resist for at least 30 seconds.
Hence, EM waves are deflected by neither electric field nor magnetic field.

Note: Electromagnetic waves are such waves that are created as a result of vibrations between an electric field and magnetic field in such a way that the electric field and magnetic field of an electromagnetic wave are perpendicular to each other. The electromagnetic wave can travel through a vacuum i.e. it does not need a medium to propagate or travel from one place to another.
