Right! so I am trying to find the Refractive Index of liquids using a laser and diffraction grating. So under by using this formula and deriving it further from here we can measure the RI. Here is the image for that. This it where it comes from. t = thickness of container (constant) cos θ...

Hi, Could someone please tell me how to derive this formula by using Wave Phenomenon d = t sin θ [ 1 - (n cosθ / n' cosθ)] I think some of it is derived using Brewster's Principle and the Refractive Index but I cannot tell how? Thanks.

Ok I will try that. Thanks guys!

How can we calculate the slipping of an object down an inclined plane?

ok i see. But is there no formula or pattern it follows?

Yes I have studied waves and resonances but I don't understand what is going on with the patterns of the cymatics

Hi, Could someone please help me about what is the physics concept behind Cymatics. Is there a formula which establishes the patterns form on a liquid when the frequency or amplitude are changed? Thanks.

Thank you soooooooooooooooo much ! :) :)

Thank You ! :)

If the Pendulum doesn't follow Harmonic Motion can we still use the formula 1) T = 2π Root(L/g) ? 2) If not, how can I calculate gravity g?

Thank you so so so so so much. Thats reallllllllllly helpful! :)

Thanks a lot Nidum but what do you mean analyze it mathematically?

Actually I am working on a particular type of pendulum called the Flying Pendulum. I did not find anything on the internet on the physics behind its working and so I am trying to prove that in order for a clock to function, the movement has to be isochronous! The pendulum should follow SHM. I...

Hi, I was wondering if someone could please help me to understand : 1) How can I prove that a Pendulum is following SHM? 2) Also, does being isochronous also mean that the pendulum is following SHM? Thank You very much.
