Answer:
(a) False
(b) True
(c) True
(d) True
(e) True
(f) True
Explanation:
(a) Maxwell's equations not only applies to constant fields but it applies to both the fields, i.e., Time variant field as well as Time Invariant field.
(b) We make use of the Modified form of the Ampere's law and Faraday's Law to derive the wave equation.
(c) Electromagnetic waves contains both the electric and magnetic fields and these fields oscillates at an angle of [tex]90^{\circ}C[/tex] to the direction of wave propagation.
(d) In free space both the electric and magnetic fields are in phase while considering electromagnetic waves.
(e) In free space or vacuum, the expression for the speed of light in terms of electric and magnetic field is given as:
[tex]c = \frac{E}{B}[/tex]
Thus the ratio of the magnitudes of the electric and magnetic field vectors are equal to the speed of light in free space.
(f) In free space or in vacuum the energy density of the electromagnetic wave is divided equally in both the fields and hence are equal.
Maxwell's equations doesn't only apply to fields that are constant over time.
It is true that the wave equation can be derived from Maxwell's equations.
It is true that Electromagnetic waves are transverse waves.
It is true that In an electromagnetic wave in free space, the electric and magnetic fields are in phase.
It is true that In an electromagnetic wave in free space, the ratio of the magnitudes of electric and magnetic field E and B is equal to c.
It is true that In an electromagnetic wave in free space, the electric and magnetic energy densities are equal.
What is Maxwell's equations all about?
Maxwell's equations serves as a partial differential equations which expressed the relationship between electric and magnetic fields to each other
It should be noted that Maxwell's equations does not only applies to constant fields, it also applies tothe fields, i.e. time variant field as well as Time Invariant field.
