Answer:

The property of the wave marked X is related to the source of the wave

Explanation:

The source of of origin of waves

Electromagnetic wave are waves that consists of varying electric and magnetic field that vibrate perpendicular to each other and to the direction of propagation of the wave and they are therefore transverse waves and transfer energy

Electromagnetic waves originate from the vibration of charged particles that gives off varying electric and magnetic fields

Mechanical waves are defined as waves that require a material medium such as air, water, metal, plastic, stretched leather, or wood to propagate

Mechanical waves originate from vibration of the particles of a medium

Sound waves which is a form of longitudinal mechanical waves that propagates by the vibration of the particles of a given medium about a point parallel to the direction of propagation of the wave.

Due to the cylindrical symmetry of this problem, the induced electric field E⃗ (R,t) can depend only on the distance R from the

It is to be noted that the electric field that has been induced is (-B₁ A/2 $\pi$ R)θ. This is obtained by using the vector units in the Cylindrical Coordinate System.

<h3>What are Cylindrical Coordinates?</h3>

Cylindrical Coordinates are simply defined as a component of a coordinate system that is used to locate a location in space using its polar coordinates and vertical distance from the polar plane.

<h3>How is the induced field arrived at?</h3>

The formula for Induced Electric Field is given as:

∫ E · dl = ∈

If we replace ∈ with -B₁A and 2 $\pi$ R for dl then

∫ E · dl = -B₁A. Thus, we can state that

E∫ dl = -B₁A

Replacing or substituting 2 $\pi$ R for ∫ dl ·E(2πR) = - B₁A

We can thus rearrange the equation to read:

E · E = ( $\frac{-B1A}{2\pi R}$ )θ

It is to be noted that the circumference of a circle is the integral of the length of the element. While θ, which in this case is the unit vector refers to the Cylindrical Coordinate and the direction of the electric field.
