List of top Physics Questions on Electromagnetic Waves asked in NEET (UG)

એક ઇલેક્ટ્રોમેગ્નેટિક તરંગનું વિદ્યુત ક્ષેત્ર \( E_x = E_0 \sin(kz - 2\pi \times 10^6 t) \) V m⁻¹ છે, જ્યાં \(\varepsilon_r = 9\). નીચેનામાંથી અયોગ્ય વિકલ્પ કયો છે:

एक हानिरहित परावैद्युत माध्यम में गमन करती वाली एक विद्युतचुम्बकीय तरंग के लिए परावैद्युत स्थिरांक \(\epsilon_r=9\) है और विद्युत क्षेत्र \[ E_x=E_0\sin(kz-2\pi\times10^6 t)\,Vm^{-1} \] दिया गया है। निम्नलिखित विकल्पों में से, गलत विकल्प है :

The electric field in a plane electromagnetic wave is given by \(E_z = 60 \cos(5x + 1.5 \times 10^{10} t)\) V/m. Then expression for the corresponding magnetic field (\(B_y\)) is (here subscripts denote the direction of the field) is:

In an electromagnetic wave in free space the root mean square value of the electric field is E_rms = 6 V/m. The peak value of the magnetic field is
