The electric field of an electromagnetic wave in free space is represented as \( \vec{E} = E_{0} \cos(\omega t - kz) \, \hat{i} \). The corresponding magnetic induction vector will be:

An alternating voltage of amplitude \( 40 \, \text{V} \) and frequency \( 4 \, \text{kHz} \) is applied directly across the capacitor of \( 12 \, \mu \text{F} \). The maximum displacement current between the plates of the capacitor is nearly:

The electric field in an electromagnetic wave is given by \( \vec{E} = \hat{\imath} \, 40 \cos \omega \!\left( t - \frac{z}{c} \right) \, \text{N C}^{-1} \). The magnetic field induction of this wave is (in SI unit):

A plane EM wave is propagating along \( x \) direction. It has a wavelength of \( 4 \, \text{mm} \). If electric field is in \( y \) direction with the maximum magnitude of \( 60 \, \text{V m}^{-1} \), the equation for magnetic field is:

Arrange the following in the ascending order of wavelength:
A. Gamma rays \( (\lambda_1) \)    B. x – rays \( (\lambda_2) \)
C. Infrared waves \( (\lambda_3) \)    D. Microwaves \( (\lambda_4) \)
Choose the most appropriate answer from the options given below:

Given below are two statements:
Statement I: Electromagnetic waves carry energy as they travel through space and this energy is equally shared by the electric and magnetic fields.
Statement II: When electromagnetic waves strike a surface, a pressure is exerted on the surface.
In the light of the above statements, choose the most appropriate answer from the options given below:
