In si units, the electric field in an electromagnetic wave is described by ey = 112 sin(1.40 107x − ωt). (a) find the amplitude of the corresponding magnetic field oscillations. µt (b) find the wavelength λ. µm (c) find the frequency f. hz

Explanation:

The electric field in an electromagnetic wave is described by:

The general equation is given by :

Here,

The amplitude in electric field is

Propagation constant,

is the angular frequency

(a) The amplitude of the corresponding magnetic field oscillations is given by :

(b) We know that the propagation constant is given by :

(c)

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
