<u>Answer:</u> The frequency is directly proportional to energy of the wave.
<u>Explanation:</u>
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
The equation that links energy of the particle and frequency of the particle is given by Planck's equation, which is:
where,
E = energy of the particle
h = Planck's constant
= frequency of the particle
Hence, the frequency is directly proportional to energy of the wave.
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: 58.8235 km/h
speed = distance/time
the distance is 10 km
the time is 10 minutes
the unit is not correct, so we first change minute to hour
so 10/60 is 0.166667, rounded to 0.17.
10 km/ 0.17 hours =
