AI Thread Summary
To calculate the frequency of a light wave with an energy of 2.50x10^-14 Joules, one can use the formula E = h * f, where E is energy, h is Planck's constant, and f is frequency. The discussion highlights a user's request for assistance in solving this physics problem, indicating a lack of familiarity with the concepts involved. Another user suggests searching online for "photon energy to wavelength" as a helpful resource. The interaction emphasizes the importance of using available tools for learning and problem-solving in physics. Engaging with online resources can enhance understanding of such calculations.

Hi guys,

I'm new to the forum, and I was recently asked this question by my friend:

If a light wave has 2.50x10 to the -14 Joules of energy, what is its frequency?


I'm no good at physics, so I was wondering if you guys could give me a hand. I'm completely clueless.


Thanks,

Please Google photon energy to wavelength. I doubt that you don't know how to use Google, but will cut you a break this time if you couldn't come up with the search terms.
 
@berkeman Thanks, I'll try it.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
