Question

2. Deseribe fieldo)or radiaion rosdusced by each the following (a) A stationary charg A moving change, moving with constant velocity along the x-avis (c) A charge accelerating along the x-direction. 3. (a) A ray of light strikes a boundary between one medium and another. State the various phenomenon that may occur (b) Construct a diagram with two mirrors are perpendicular to each other and one is placed along +x and the other along ty direction, both at the origin. An incident ray makes an angle of 30 degrees with the horizontal mirror. Find the angle the outgoing ray makes with the y-axis after it reflects from each mirror

Explanation / Answer

2)

(a)A stationary charge will only create an electric field. No radiations will be produced.
Because electric fields are produced by any single charge but magnetic fields are produced by moving charge only.

(b)A moving charge will produce both electric and magnetic fields. Both perpendicular to each other.

(c)An accelerating charge will have noth electric and magnetic fields and along will also create electromagnetic radiation around it.
The electric and magnetic field will oscillate perpendicular to each other and the direction of motion and gives rise to electromagnetic radiation.
