Possible Variables in a Planck's Constant Practical?

[Procrastinate]

I'm doing a practical for Physics and writing a report on it so I chose Planck's constant. I know that one of the variables I can change could be the frequency of the oscillating waves but my teacher says that you should consider two variables if you want to do well.

I don't know what other variable to consider in this case since I'm only just starting to leaern abut Planck's constant and the Photoelectric effect.

Thanks in advance.

Your description is far too vague for us to really be able to help you. WHAT question specifically are you trying to answer about Planck's constant? Also, WHAT variables are you referring to? I can guess what, "the frequency of the oscillating waves" might refer to in this context, but it would be far more helpful if you made that clear.

I am going to assume that a physics "practical" is an assignment in which you are asked to research a topic of physics and write a report about it (which is a pretty strange way of going about learning physics if you ask me).

I would suggest considering the intensity or brightness of the light source as another variable to explore in your practical on Planck's constant. This is because the intensity of light can affect the energy of the photons being emitted, which in turn can affect the results of the Photoelectric effect. By varying the intensity of the light source, you can observe how it affects the number of electrons emitted and the kinetic energy of those electrons. This can provide valuable insights into the relationship between energy and frequency, which is a key concept in understanding Planck's constant. Additionally, you could also consider the type of metal used in the experiment as a variable, as different metals have different work functions which can also impact the results of the Photoelectric effect. By controlling and manipulating these variables, you can further explore the relationship between energy, frequency, and Planck's constant, leading to a more comprehensive and accurate report on your practical.
