The velocity of the light wave is determined by the characteristics of the free space such as permeability and permittivity of free space. The expression of the velocity of the electromagnetic wave is given as 1/ ./mu0 epsilon 0
mu0 = 4 pi x 10 -7 H/m and epsilon 0 = 1/ 4pi*9*109 F/m
Plugging these values we get the velocity as 3 x 108 m/s
./ is the square root symbol.

Electro magnetic force?
The electromagnetic force is one of the fundamental forces in nature, responsible for interactions between charged particles. It encompasses both electric and magnetic forces, which are manifestations of the same fundamental force. It plays a crucial role in a wide range of phenomena, from holding atoms together to generating light and other electromagnetic waves.
Is electric and electro magnetic energy the same thing?
While electric energy refers to the flow of electric charge, electromagnetic energy encompasses both electric and magnetic fields that propagate through space as electromagnetic waves. In essence, electric energy is a component of electromagnetic energy, alongside magnetic energy.
Is velocity for waves different than speed?
No, velocity refers to the speed of an object in a specific direction. In the context of waves, velocity is the speed at which a wave moves through a medium in a particular direction. So, in the case of waves, velocity and speed refer to the same concept.
Which of the two charged particles of the same mass but different velocity will be deflected the most in magnetic field and why?
The charged particle with the higher velocity will be deflected the most in a magnetic field. This is because the magnetic force experienced by a charged particle is directly proportional to its velocity. Therefore, a higher velocity particle will experience a greater magnetic force and be deflected more.
How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
A decrease in velocity of the waves will cause a decrease in frequency and a decrease in wavelength as the waves enter shallow water. This is due to the relationship between velocity, frequency, and wavelength which is defined by the equation: velocity = frequency x wavelength.
Compared to the velocity of radio waves the velocity of visible light waves is?
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).

How do telescopes pick up electro- magnetic waves in space?
-- They pick up light waves the same way telescopes, cameras, and your eyes do here on Earth. -- They pick up radio waves from the control center by means of antennas mounted under the optical assembly.
Is the velocity of light more than velocity of radio waves?
No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
Is electric and electro magnetic energy the same thing?

Does the velocity of two different waves in the same medium be equal?
no it is not equal
Which of the two charged particles of the same mass but different velocity will be deflected the most in magnetic field and why?
The charged particle with the higher velocity will be deflected the most in a magnetic field. This is because the magnetic force experienced by a charged particle is directly proportional to its velocity. Therefore, a higher velocity particle will experience a greater magnetic force and be deflected more.
In any one material all electromagnectic waves have the same?
In any one material all electromagnetic waves have the same velocity. Electromagnetic waves traveling through a medium travel at the same speed.
How are light and radiant energy the same?
there both in the electro magnetic spectrum. the visable section is the colours we see and there are 3 other types on each end. the spectrum is : Radio waves Micro waves ( funnily enough they are used in microwaves) Infra-red radiation Visable light ultraviolet x-ray gamma ray
Electromagnetic waves travel at the same what?
Electromagnetic waves in a vacuum all travel at the same velocity, the speed of light (about 3 x 10^8 m/s).
How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
A decrease in velocity of the waves will cause a decrease in frequency and a decrease in wavelength as the waves enter shallow water. This is due to the relationship between velocity, frequency, and wavelength which is defined by the equation: velocity = frequency x wavelength.
