Those interested in the Attenuation constant electromagnetic wave category often ask the following questions:

### ☑️ Is the speed of light in an electromagnetic wave constant?

• Any wave from the electromagnetic spectrum travels at a constant speed of light. Other properties such as frequency, energy, wavelength vary depending on the type of wave and the source producing them. But the velocity remains constant.

### ☑️ Is the speed of electromagnetic waves constant?

• The speed of an electromagnetic wave is a constant, 3.0 x 10⁸ m/s. The wavelength of a wave is 0.3 meters. What is the frequency? At night, a lamp appears brighter to someone sitting near it than to an observer across the room.

### ☑️ Is an electric field associated with an electromagnetic wave constant in time?

No, the electric field oscillates in magnitude and direction as it propagates in the electromagnetic wave.

### ☑️ Why do higher frequencies wave have more attenuation?

For radio frequencies, there is more attenuation through the atmosphere for higher frequencies because they are better absorbed by the moisture in the air.

### Is the speed of a wave constant?

The wave speed, v, is how fast the wave travels and is determined by the properties of the medium in which the wave is moving. If the medium is uniform (does not change) then the wave speed will be constant. The speed of sound in dry air at 20 C is 344 m/s but this speed can change if the temperature changes.

### Can the wave function be a constant?

• A valid wavefunction in the position representation is one which is continuous. If we are going to have valid wave function which is constant, it has to exist in a space with boundary conditions which allow it to be constant: so it has to exist in a periodic (compact) space.

### Is a tv wave an electromagnetic wave?

It depends what you mean by TV wave. If you mean the transmission of television signals, then yes. An electrical signal can be transmitted from about 10kHz, so fits into the low end of the electromagnetic spectrum. The frequency for TV carrier signals will vary around the world, but they're typically VHF and UHF, so from 30MHz to 3GHz. Of course, digital systems and satellite distribution mean higher frequencies - in the microwave spectrum (higher frequency than light).

### Is an electromagnetic wave a sound wave?

An electromagnetic (EM) wave is not a sound wave.A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy.The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields.This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.

### Is a sound wave an electromagnetic wave?

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.

### Is a string wave a electromagnetic wave?

If you mean a wave on a string, no - that's a different type of wave.

### What type of wave is electromagnetic wave?

#### What are the different types of waves in physics?

• Different Types of Waves in Physics With Examples. Waves transport energy without transporting matter. The energy transportation is carried by a disturbance, which spreads out from a source. Basically, there are three types of waves. Mechanical waves, electromagnetic waves, and matter waves.

### Electromagnetic wave is what kind of wave?

An electromagnetic wave is a wave all on it's own. They are waves that do not require a medium (any material a wave can travel through, such as a rope or a hose). Light does not need to travel through anything in order to reach your eyes. Thus you have an electromagnetic wave.
