Planck's constant

[Aria Soeprono 2F]

In the equation E=hv, I understand that h is Planck's constant, but how was this derived and what exactly does it mean?

[Elisa Bass 4L]

I believe Lavelle said that Planck’s constant is the proportionality constant derived from experimental data on the relationship between energy and frequency, since energy and frequency are proportional. If you were to graph them both on a regular coordinate plane, the data points would be in a straight line extending from the origin with a slope equal to Planck’s constant.

Can you explain each part of this equation and the relationships between each variable? I want to make sure I'm understanding it correctly.

[Adrienne_4F]

E is the energy of the particle or photon, with the units joules.
H is just Planck's constant, which is 6.63 X 10^-34 joules X second.
V is the frequency, with the units Hertz or S^-1.

Energy and frequency are directly proportional, therefore when frequency increases, energy increases.

Will I ever have a need to convert Hertz to Joules? or would they stay separate?

[Athena L 1B]

If you ever needed to, you would just need to multiply the hertz by something that has units J x s, which planck's constant has.
