प्रश्न
Write the relation between the velocity of propagation and the magnitudes of electric and magnetic fields.
उत्तर
The relation between the velocity of propagation and the magnitudes of electric and magnetic fields is given by
`c=E/B`
Here,
c = Velocity of the electromagnetic wave
E = Magnitude of the electric field
B = Magnitude of the magnetic field
Note that electromagnetic waves propagate with the speed of light. So, in this case, c is the speed of light.

Velocity of light in glass is 2 × 108 m/s and in air is 3 × 108 m/s. If the ray of light passes from glass to air, calculate the value of critical angle.
Suppose a charged particle moves with a velocity v near a wire carrying an electric current. So, a magnetic force acts on it. If the same particle is seen from a frame moving with velocity v in the same direction, the charge will be found to be at rest. Will the magnetic force become zero in this frame? Will the magnetic field become zero in this frame?
