For this case we have by definition:
v = λf
We observe that we have a linear relationship, where λ is the constant of proportionality.
We have then:
Answer:
The variable that is directly proportional to the frequency is λ, the wavelength.
Answer: The frequency is directly proportional to energy of the wave.
Explanation:
Frequency is defined as the number of waves that passes a given point per second. It is expressed in Hertz. It is denoted by the symbol [tex]\nu[/tex]
The equation that links energy of the particle and frequency of the particle is given by Planck's equation, which is:
[tex]E=h\nu[/tex]
where,
E = energy of the particle
h = Planck's constant
[tex]\nu[/tex] = frequency of the particle
Hence, the frequency is directly proportional to energy of the wave.
