At a particular moment in time and space, we measure an electromagnetic wave's electric and magnetic fields. we find the electric field âe pointing north and the magnetic field âb pointing down. what is the direction of wave propagation?


Answer 1

Electromagnetic waves are a combination of oscillating electric and magnetic fields. The direction of electromegnetic wave propagation is perpendicular to the electric and magnetic fields.

What is an electromagnetic wave?

EM waves are another name for electromagnetic waves. Electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field.

Electromagnetic waves may alternatively be defined as the combination of oscillating electric and magnetic fields. The right-hand thumb rule is used to define the direction of the wave.

According to the right-hand thumb rule,

Hold a current-carrying conductor in your right hand with your thumb pointing in the direction of the current.

Then wrap your fingers around the conductor and orient them in the direction of the magnetic field lines.

Hence the direction of electromegnetic wave propagation is perpendicular to the electric and magnetic fields.

To learn more about the electromagnetic wave refer to the link;

Answer 2
Answer: Hi

perpendicular to magnetic field and electric field.

the magnetic field is always perpendicular to the magnetic field and direction of wave propagation is perpendicular to the both field.

these give us a right hand rule relating the direction .
1) keep your fingers in the direction of electric field.
2) curl your fingers toward magnetic field
3)the thumb of your hand show the direction of propagation .


so direction of the wave propagation in 'west' direction .

thanks for asking

How are SI units used in the united states?


Mostly in science classes, science laboratories, and companies
that manufacture things for export to other countries.

SI units are used very little by the common people, for things that

world that have not officially adopted the metric system. 

We are unique, along with those other two economic, industrial, and

Which of these materials is the most malleable? Select one:

A. notebook paper

B. copper

C. window glass

D. granite


Answer: B. copper


A malleable is the property of metals which can be capable of being shaped and extended by the process of beating using a hammer or by using the rollers pressure. The malleable material is capable of being altered or controlled by the external forces and influences. The malleable metal does not breaks and it is not brittle.

Copper is a metal which is malleable. It can be transformed into various shapes and forms on the basis of the malleability

Malleable basically means bendable and shapeable. notebook paper is the easiest to bend and shape

is the difference between hypothesis, theory and scientific law?


Hypothesis is what you think will happen , a theory is a system of ideas to explain something. scientific law means a statement that is based on repeated experimental observations.

A 320 kg rocket sled can be accelerated at a constant rate from rest to 1900 km/h in 2.1 s. What is the magnitude of the required net force?



Force = 80422.4 N


Given that,  

Initial speed, u = 0 m/s

Final speed, v = 1900 km/h = 527.78 m/s ( 1 km/h = m/s)

Time taken, t = 2.1 s

So, Applying equation of motion as:

According to the Newton's second law of motion:-

Mass = 320 kg


Force = 80422.4 N
