Question

In an inverse graph for wavelength versus frequency what are the units of the constant? Would they be (cm/s)/Hz or what?

Answer 1

cm/s

Step-by-step explanation:

λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.

λ = c/v which is in cm/s/Hz

But we would use just cm! Because that's how we measure the wavelength in this example.

However, the constant is c, the speed of light, which we measure as a speed, so cm/s will do.

Answer 2

Answer: centimeters per second (cm/s)

Step-by-step explanation:

The relation between the frequency and the wavelenght is:

Velocity = wavelenght*frequency.

So in a relation of wavelenght vs frequency, we will have the relationship:

Where wavelenght is Y and frequency is X

wavelenght = velocity/frequency.

So the constant is the velocity, and we know that the units of the wavelenght is cm, the unit of frequency is Hz (or 1/s), so the units of the velocity is cm/s
