Uh, I see. This makes sense -- the reflected angle = β + γ. Given that θ = β = γ, the deflected angle = 2β = 2θ. Thank you very much for your help!

γ

I see. Then given that β = γ = θ ≠ 2θ would that then mean that the angle of deflection is in fact not equal to twice the angle through which the mirror is rotated? Could it be a typo perhaps?

I see. That is what I initially thought, but then why is β ≠ θ when geometrically they seem to be equal when accounting for the isosceles triangle at the bottom of the diagram?

The angle of incidence is equal to the angle of reflection.

Hi Everyone, A question in my latest Physics I lab wishes for a proof showing that if a laser beam is incident on a mirror that is then rotated an angle θ the beam is deflected an angle 2θ. I attempted to prove this geometrically below. In the diagram the angle γ, is the angle of deflection...

Whilst South African schools do not require GERs, or anything even remotely similar, if I do decide to apply to an American University at some point in the future, whether it be as a post-graduate or undergraduate, taking the GERs online seems to be a very good idea. I haven't mentioned it in...

I had a look at the Berkeley courses, unfortunately all of the physics courses require physical attendance. The mathematics courses, however, look fairly promising, although I will have to make inquiries into how exactly the calculus courses compare to those of other universities. Harvard also...

Thanks for the reply. This is most certainly an option, the problem here, however, is that universities such as the Harvard Extension school, at least from my research, do not offer a wide enough range of courses with enough credit available in either mathematics or physics to make this a viable...

Thank you for your response. This is certainly an option, and may perhaps even be my best at this point. If I were to take the year off I would most likely concentrate on correcting my current problems, namely that of a physical disability, although I would still attempt to learn as much as...

Hi everybody,I am a math, physics, and English A-level and will be writing my final exams in October/November. My primary goal is to garner a BSc in math, physics, and computer science, before entering post-graduate study at a good research university in either math or physics, and hopefully in...

Triple majoring hopefully.

Hi Everybody, I am in my final year of high school, and want to enrol with the University of the Witwatersrand in Johannesburg, South Africa next year, and I will hopefully be going for a Bsc in computer science, math and physics. However, I have been wondering a couple of things over the...

Thank you. I will make a thread.

Hi Everybody, I currently live in South Africa and aspire to go to WITS next year, as I am in my final year of high school at the moment; however, I have a bit of an issue. You see, as my three Bsc courses I would like to take Physics, Computer Science and Math, but from my understanding...
