To make studying for your class easier, Varsity Tutors' Learning Tools offers many high school physics study help activities for you to use, including free flashcards online. If you fall behind in this introductory physics class, then you may find future physics classes even more challenging. Understanding the physics concepts you are learning now can help you perform well in later physics classes you may take in college. If you are taking a high school physics class, then not only is it important to study well to earn a great grade in your class, but it is also important to develop a deep understanding of the physics concepts you are learning. Get some studying in now with our numerous High School Physics flashcards. You by definition cannot observe any of the photons that make it to the interference pattern until they bounce off the surface and into your eye.Want to review High School Physics but don’t feel like sitting for a whole test at the moment? Varsity Tutors has you covered with thousands ofĭifferent High School Physics flashcards! Our High School Physics flashcards allow you to practice with as few or as many questionsĪs you like. Also, as far as the steam thing goes: if you can see a photon, where is the photon? It had to hit the back of your eye for you to see it. By detecting which slit it has gone through you've essentially "removed" the probability aspect of it and know for sure if it will hit left or right.
#Physics notecard how to
This is where the details get really funky and I don't exactly know how to explain this properly, but i suppose you could say it's more about detecting which slit the photon goes through rather than you yourself actually "observing" it consciously. Remember, this is done by sending only one photon through the slits at a time. Lastly, what it means to "observe" each photon before it hits the wall, thus changing the experiment. However it still made the interference pattern, showing that even though each photon hit the wall one at a time, like a particle/bullet, it actually travelled like a wave and the probability of where it hit was affected by the shape of the slits. Physicists expected that since there would be no other photons around to interfere with the behavior of the single photon, the pattern made should be like shooting bullets through the slits. In the original experiment, and your experiment, there are huge numbers of photons passing through the slits. Before we even get into what "observation" means to the experiment, you should know that in the modern version there is only one photon being "shot" through the slits at a time. What you're talking about is one of the modern versions of the experiment. Here's one of those simulations you do in a first year physics lab:
Even waves in a swimming pool make the same interference pattern when they pass through a double slit, and so this experiment helped to support the theory that light behaved like a wave. If light were only a particle, you would expect a different pattern, like shooting bullets through two slits. The experiment you have set up shows that light has wave-like properties, because the interference pattern indicates wave-like behavior is going on. Unfortunately what you're thinking of is completely different, and I'll get to that after I explain the experiment you have done. Okay, theres a few big problems with this, get ready.įirst, if you got an interference pattern, you actually have successfully replicated one of the double slit experiments, and it's the first one that was done historically (over 200 years ago!). This pretty much has me stumped as I do not understand how a photon can be particle and then transform itself back into a wave after I have observed its location past the slit.->Is this related to the quantum eraser?Īttached more pictures because I think they look kind of cool. there is an inference pattern on the background. I know the picture is unclear but trust me. If I am observing the photon passing through each slit with the steam from the humidifier->this observation creates a particle(two separate beams)->then WHY/HOW is there still an inference pattern? Here's the part that I do not understand: When you collect information about a photon(observe it)->it becomes a particle when the steam hits the laser beam->the photon becomes a particle->see how the laser beam is split in two Third reaction->let's make it more cool with steam from a humidifier Second reaction->this is pretty f'ing cool The setup->a basic laser from walmart aimed through two slits in a notecardįirst reaction->really astonished to be able to replicate the experiment that triggered such a tremendous advancement in science and technology
