What characteristics of EM waves did you discover?
Answers
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.
Further explanation
- 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: reflection
Refraction
Energy
Speed
Explanation:
Reflection results when em wave hits a plane surface and returns in the same angle it incident
Refraction is the change in velocity and direction of em wave as it crosses boundaries of different medium
The energy of em wave is evenly distributed in electric field and magnetic field
The speed of em wave is the same as 3×10^8

As absurd as the concept is, we must assume that a croissant
can fall 300.5 meters through the moisture-laden, perfumed and
polluted Parisian air with no air resistance whatsoever.
Acceleration due to gravity on Earth: 9.8 m/s²
Distance in clean,
unimpeded free-fall = (1/2) (acceleration) x (time²)
300.5 m = (1/2) (9.8 m/s²) (T²)
Divide each side
by (4.9 m/s²): (300.5 m) / (4.9 m/s²) = T²
Take the square root
of each side: T = √(300.5/4.9) (s²)
= 7.831 seconds .

The answer is:
A) Biotic and non living
The explanation:
when Biotic refers to the component of living things that are part in ecosystem. Nonliving meaning a certain thing or the table does not have any life but it's biotic.
and we here have a wooden table that is derived from a living thing like a tree and it is nonliving as its a table.

"VLBI" stands for "Very Long Baseline Interferometry". The idea
is that the signal is picked up by two receivers, separated by some
distance. The tiny difference in the time the signal shows up at the
two places is used for a very precise calculation of the direction it's
coming from.
