Intensity of a wave is a scalar quantity because it only has one value that represents the amount of energy transferred per unit area per unit time. It does not have a direction associated with it like a vector quantity.

Is amplitude scalar or vector?

Amplitude is a scalar quantity. It represents the maximum displacement of a wave from its equilibrium position and does not have a direction associated with it.


Why amplitude is scalar?

Amplitude is a scalar because it is a magnitude that represents the maximum value of a wave. It does not have a direction associated with it, unlike vector quantities which have both magnitude and direction. This makes amplitude a scalar quantity.


What are characteristics of amplitude?

Amplitude is the measure of the magnitude of a wave, representing its maximum displacement from the equilibrium position. It is a scalar quantity and is always a positive value. Amplitude determines the intensity or loudness of a wave in sound waves and the brightness or intensity of a wave in light waves.


Is wavelength a scalar or vector?

Wavelength is a scalar quantity, meaning it has magnitude but no direction. It is a measure of the distance between two consecutive points on a wave (e.g., crest to crest or trough to trough) and does not have a specific direction associated with it.


Is amplitude a vector or scalar quantity?

Yes, because amplitude is the maximum displacement of a wave from its rest position and displacement has direction and it's a vector. hence, amplitude is a vector. That is a bit like saying a weigh scale is a vector, because it goes up and down as you get on and off it. As with weight, pressure, etc, amplitude is the scale of wave magnitude against which particular waves are measured. Frequency is the vector, because you are measuring from one peak to the next, so the "length" gives it "direction," ie. a vector.

Is frequency a scalar or vector quantity?

Frequency is a scalar quantity,now comes the question how to decide which one is scalar and which one is vector,scalar quantities are those which only have values and we can't assosciate any direction to them ,whereas,vector quantities are those which have values as well as directions assosciated with them.For example,time is a scalar quantity because we say its 10:30 pm we never say its 10:30 pm south-west,where as if we say the wind is blowing at 30 m/sec towards north(this particular thing is called velocity)then it is a vector quantity. some more examples:-300 degree celcius(scalar),76.8%(scalar),5 meters north(vector)

How does the expression for the velocity of the longitudinal wave differ from transverse wave?

The waves are the scalar and vector parts of Quaternion derivatives: [d/dr, DEL]2 [b,B] = The Longitudinal wave (d2/dr2 - DEL2)b - 2d/dr DEL.B is a scalar wave The Transverse wave (d2/dr2 - DEL2)B + 2d/dr( DEL b + DELxB) is a vector wave.


Waves that are comboination of transverse and longitudinalwaves are called?

Traditionally such waves are called surface waves. They are technically Quaternion waves consisting of a scalar (longitudinal) wave and a vector (transverse) wave.


What two kinds of fields make up an EM wave?

An electric field and a magnetic field make up an electromagnetic wave. These fields are perpendicular to each other and oscillate in phase as the wave propagates through space.


What is the formula of wave intensity?

Not sure what formula you are looking for. Wave intensity is given by the amplitude of the wave.


How does the amplitude of a sound relate to its intensity?

The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the amplitude of sound pressure variations. Intensity I = sound pressure squared p2.
