QAIPM-2012-Ph-1669: NEET 2012 Physics - Class 12 AIPM-2012-Ph-1669 Solution: The ratio of amplitude of magnetic field to the amplitude of…
The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vacuum is equal to the speed of light in vacuum reciprocal of speed of light in vacuum the ratio of magnetic permeability to the electric susceptibility of vacuum unity
Multiple Choice Options
- A the speed of light in vacuum
- B reciprocal of speed of light in vacuum
- C the ratio of magnetic permeability to the electric susceptibility of vacuum
- D unity
Step-by-Step Verified Solution
If the speed of light c then
E 0 = B 0 c
_ B 0 E 0 = 1 c
Hence ratio of amplitude of magnetic field to amplitude of electric field for electromagnetic wave in a vacuum is reciprocal of speed of light.
