NEET2025:The electric field in a plane electromagnetic wave is given byEz = 60 cos (5x + 1.5 × 109

Description

The electric field in a plane electromagnetic wave is given by
Ez = 60 cos (5x + 1.5 × 109 t) V/m.
Then expression for the corresponding magnetic field is (here subscripts denote the direction of the field) :
(1) By = 2 × 10–7 cos (5x + 1.5 × 109 t)T (2) Bx = 2 × 10–7 cos (5x + 1.5 × 109 t)T
(3) BZ = 60cos (5x + 1.5 × 109 t)T (4) By = 60 sin (5x + 1.5 × 109 t)T

Frequently Asked Questions

How to prepare for NEET Physics?

For NEET Physics preparation, focus on NCERT textbooks first, then move to reference books. Create a topic-wise study plan covering Mechanics, Thermodynamics, Electromagnetism, Optics, and Modern Physics. Solve previous years’ questions and take regular mock tests. Pay special attention to conceptual clarity and numerical problem-solving skills.

What is the difference between electric potential and electric potential energy?

Electric potential is the electric potential energy per unit charge, measured in volts (V). It’s a property of a point in space. Electric potential energy is the energy possessed by a charge due to its position in an electric field, measured in joules (J). It depends on both the charge and its position.

What is the Doppler effect?

The Doppler effect is the change in frequency or wavelength of a wave for an observer moving relative to the source of the wave. When the source moves toward the observer, the frequency increases (wavelength decreases). When the source moves away, the frequency decreases (wavelength increases). This effect explains why the pitch of a siren changes as it passes by.
