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.

Which of these materials is the most malleable? Select one:
A. notebook paper
C. window glass
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
is the difference between hypothesis, theory and scientific law?
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
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
