The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.
<h3>What is meant by electromagnetic waves?</h3>
Electromagnetic waves are forms of energy that are invisible and travel throughout the universe. However, some of the effects of this energy are visible. The light that we see is a component of the electromagnetic spectrum.
Electromagnetic waves, or EM waves, are produced by vibrations between an electric field and a magnetic field. In other words, electromagnetic waves are made up of oscillating magnetic and electric fields.
<h3>How do you calculate the speed of an electromagnetic wave?</h3>
The wavelength and frequency of any periodic wave are used to calculate its speed. v = λf.
In free space, the speed of any electromagnetic wave is equal to the speed of light, c = 3 108 m/s.
The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.

Answer:
The speed is
Explanation:
From the question we are told that
The magnetic field is
The electric field is
Generally the speed of the electron is mathematically represented as
Substituting values
Answer:
The temperature of the cooler substance was close to the room temperature. Therefore, the system experienced less change
Explanation:
Generally, in a closed system containing two bodies at different temperatures, there is a flow of heat energy from the body at a higher temperature to the body at a lower temperature. The effect is more significant when there is a large temperature difference between the bodies. However, if the temperature difference is small or insignificant, the change will be less.
Answer:
d) KEe = KEp
Explanation:
According to the law of conservation of energy, the electric potential energy is converted into the kinetic energy of the particle:
Here, q is the particle's charge and V is the potential difference.
The charge of the electron is -e. So:
The charge of the proton is e. So:
So
Answer:
Answered
Explanation:
( in the south direction)
(in the west direction)
so direction of v_1 and v_2 are north and west respectively.
we used the formula for relative velocity
is the velocity of B with respect to A.
