# Graphing - photonic Energy Vs Frequency

1. The problem statement, all variables and given/known data

"What is the relationship between the energy of a photon and its frequency"

then

"Qualitively graph photonic energy versus frequency. No values are required. The Slope does not need to be specific."

2. Relevant equations

we are given a graph with no values, the frequency is on the X-Axis while the photonic energy is on the Y-Axis

3. The attempt at a solution

i have drawn a straight line at a diagonal, which goes through the origin, this would infact make the photonic energy directly proportional to the frequency.

I am not sure if this is correct?, are you please able to assist me to achieve the correct answer

thanks

Sounds good. (What's the energy of a photon of given frequency?)

i am not given any frequencies?

What's the general relationship between photon energy and frequency?

5. Aug 9, 2011

### MRFISCHERRULZ

If the frequency increases, the photon energy will increase

directly proportional?

Yes. The energy of a photon is related to the frequency of the radiation by Planck's relationship: Energy = Planck's constant X frequency.
