In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields.
Do all electromagnetic waves have the same amplitude?
Most recent answer
No, radiation with a high amplitude always has a higher energy density than radiation with a low amplitude. … Example: Microwave frequency = 3 Ghz, X ray frequency = 3 EHz, S = 1 W/m2 in both cases, consequently the amplitude of E is identical for both frequencies, and so is the amplitude of H.
Are electromagnetic waves neutral?
But EM waves are affected by external electric and magnetic fields. … According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .
Is amplitude half the wavelength?
AMPLITUDE AND WAVELENGTH
Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form.
What is the fastest electromagnetic wave?
What is the same in all electromagnetic waves?
Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
Can electromagnetic waves affect light?
According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .
Does wind affect electromagnetic waves?
Though wind directly does not affect radio waves, it does effect the refraction (the bending of waves) capabilities of the medium which is what leads aberrations in radar propagation. Refraction is always present in the atmosphere and needs to be accounted for in radar (which uses radio waves).
Do photons travel in a straight line?
Photons do not travel in straight lines. To be technical, photons are both waves and particles. … Therefore, photons travel along the curvature of space. Gravity does not deflect photons, but gravity bends spacetime along which photons travel.
Is amplitude directly proportional to frequency?
Frequency is inversely proportional to amplitude.
Does light have amplitude?
Light is an electromagnetic wave, so it has an amplitude measured in volts per meter in one direction perpendicular to its propagation direction, and an amplitude measured in tesla in the remaining perpendicular direction. Both amplitudes can have any value, but their ration is fixed.
What happens to frequency when amplitude increases?
What is the relation between the amplitude and the frequency of a wave? The amplitude and the frequency of a wave are independent of each other. The amplitude and the frequency of a wave are equal. The amplitude decreases with an increase in the frequency of a wave.
Which waves travel the fastest?
This is the fastest kind of seismic wave, and, consequently, the first to ‘arrive’ at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air.
Which light waves travel the fastest?
Electromagnetic waves (and therefore radio waves) travel about one million times faster than sound waves.
What are the 7 electromagnetic waves in order?
This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
