STATEMENT-1 : An oscillating charge must give out electromagnetic waves. STATEMENT-2 : Accroding to Maxwell's theory. Accelerated charges raadiates electromagnetic wave

STATEMENT-1 : Electromagnetic waves may set tiny charged particies into motion. STATEMENT-2 : Electromagnetic waves have momentum and energy

A : High frequency electromagnetic waves are detected by some means based on physical effects they produce on interacting with matter. R : The oscillating fields of an electromagnetic wave can accelerate charges and can produce oscillating currents therefore, an apparatus designed to detect EM waves is based on this fact.

(A) : In an electromagnetic wave, the electric and magnetic fields oscillate in phase (R) : In an electromagnetic wave, the electric and magnetic fields oscillate out of phase.

(A) : Dipole oscillations produce electro­magnetic waves. (R) : Accelerated charge produces electro­magnetic waves.

Assertion : Electromagnetic waves carry energy and momentum Reason : Electromagnetic waves can be polarised.

A : In an electromagnetic wave the energy density in electric field is equal to energy density in magnetic field. R : Electromagnetic waves are transverse in nature.
