The characteristics of electromagnetic waves typically represent as follows:
- There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
- The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
- The shape of electromagnetic waves is transverse waves.
- It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
- The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
- The universal constant of the velocity of electromagnetic waves in a vacuum is
- The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
- Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.
- Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
- From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
- Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
- As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
- Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
- Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

Answer:
The lighter frog goes higher than the heavier frog.
The lighter frog is moving faster than the heavier frog
Explanation:
If both frogs have the same kinetic energy when they leave the ground, the following equality applies:
Now, if the only force acting on the frogs is gravity, when they reach to the maximum height, we can apply the following kinematic equation:
When h= hmax, the object comes momentarily to an stop, so vf =0
Solving for hmax:
As the lighter frog, in order to have the same kinetic energy than the heavier one, has a greater initial velocity, it will go higher than the other.
As a consequence of both having the same kinetic energy, the lighter frog will be moving faster than the heavier frog.
