What two kinds of fields make up an EM wave?
scalar field and vector field
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.
What point of a wave has negative amplitude?
The trough of a wave appears to have a negative amplitude. However, because amplitude is a distance measurement, which is a scalar quantity having only magnitude, it has no sign.
How are wave speed frequency and wave length related to the wave amplitude?
Frequency is the amount of bumps there are in the wave. The higher the frequency the lower the wave length and vise versa. some equations are E=hv C=vw h=Plancks Constant(6.626x10 to the -34) C=3.0x10 to the power of 8
What are the different kinds of waves?
There are many different waves depending on the characterization category being studied. If waves are being characterized by the matter that they travel these waves include electromagnetic, physical, and longitudinal waves.
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)
Is wave a vector quantity?
Yes

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.
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.

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 point of a wave has negative amplitude?
The trough of a wave appears to have a negative amplitude. However, because amplitude is a distance measurement, which is a scalar quantity having only magnitude, it has no sign.

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.
What are parallel and perpendicular polarisations?
Parallel polarisations are the divergence of the vibrations (Del . dV/dr) and Perpendicular polarisations are Curl of the vibrations (Del x dV/dr). The parallel polarisations is associated with the scalar wave and the perpendicular polarisations are associated with the vector wave.
What do we see that the amplitude of a wave produces?
The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
