QNEET-2024-Ph-172: NEET 2024 Physics - Class 12 NEET-2024-Ph-172 Solution: If the ratio of relative permeability and relative permittivity …

If the ratio of relative permeability and relative permittivity of a uniform medium is 1:4. The ratio of the magnitudes of electric field intensity (E) to the magnetic field intensity (H) of an EM wave propagating in that medium is (Given that μ0/ϵ0=120π\sqrt{\mu_0/\epsilon_0} = 120\pi): 30π:130\pi:1 1:120π1:120\pi 60π:160\pi:1 120π:1120\pi:1

Multiple Choice Options

  • A 30π:130 \pi: 1 30 � : 1
  • B 1:120π1: 120 \pi 1 : 120 �
  • C 60π:160 \pi: 1 60 � : 1
  • D 120π:1120 \pi: 1 120 � : 1
