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.
Do electromagnetic waves have amplitude?
In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields.
Do all light waves have the same amplitude?
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength. Both Wave 1 and Wave 2 have the same wavelength but different amplitudes. The wavelength of light is an important property for it is this that determines the nature of the light.
Do electromagnetic waves have the same frequency?
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
What do sound waves and electromagnetic waves have in common?
Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.
Where is energy stored in electromagnetic waves?
The E and B fields, along with being perpendicular to each other, are perpendicular to the direction the wave travels, meaning that an electromagnetic wave is a transverse wave. The energy of the wave is stored in the electric and magnetic fields.
What type of waves are light waves?
Light waves move as transverse waves (see diagram of a transverse wave) and can move through a vacuum (empty space) at a speed of approximately 186,000 miles per second. Light has both magnetic and electric fields. Scientists call this electromagnetic radiation (light).
Which color has the greatest amplitude?
(An easy way to remember this is the mnemonic ROYGBIV: red, orange, yellow, green, blue, indigo, violet.) The amplitude of light waves is associated with our experience of brightness or intensity of color, with larger amplitudes appearing brighter.
Which waves have the greatest amplitude?
In a longitudinal wave, particles of the medium move back and forth in the same direction as the wave. Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. The closer together the particles are, the greater the amplitude of the wave.
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.
Does higher frequency mean higher energy?
Frequency –> Energy
The higher the frequency of light, the higher its energy. We know from the problems above that higher frequencies mean shorter wavelengths. … High frequency light has short wavelengths and high energy. X-rays or gamma-rays are examples of this.
Do higher frequency waves travel faster?
Comparing two waves of the same wavelength, a higher frequency is associated with faster movement. Comparing two waves of different wavelengths, a higher frequency doesn’t always indicate faster movement, although it can. Waves of different wavelengths can have the same frequency.
Why electromagnetic wave can travel in vacuum?
An EM wave can travel without a material medium—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever. Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.
What are the similarities and differences between sound waves and electromagnetic waves?
Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.13 мая 2014 г.
Do sound waves travel faster than electromagnetic waves?
Unlike water waves, electromagnetic waves always travel at the same speed (3 hundred million metres per second) and sound waves all travel at the same speed in a given medium (for example, approximately 340 metres per second in air).2 мая 2011 г.
