Measuring Speed of Light with Glass Plate

AI Thread Summary
To determine the speed of light through a glass plate, the index of refraction is essential, as it relates the speed of light in the medium to that in a vacuum. The formula V = C/N is used, where V is the speed of light in the glass, C is the speed of light in a vacuum (approximately 3x10^8 m/s), and N is the index of refraction of the glass. The discussion clarifies that the goal is to measure the speed of light in the glass rather than in a vacuum. Accurate values for the index of refraction are necessary for precise calculations. Understanding these relationships is crucial for experimental physics involving light propagation in different media.

How can I determine the speed of light from a glass plate? I have the the numbers that I compared the average experimental value of the index of refraction with the general range of the index of refraction of glass.

are you trying to find out speed of light though a glass plate? I am not sure what your question is.

yes, that's correct.
 
Is the problem to find the "speed of light (in vacuum)" or "the speed of light in the glass plate". The index of refraction is the ratio of speed of light in the glass plate to the speed of light in vacuum.
 
V = C/N... c being speed of light (3x10^8) and N being being whatever the index of refraction is of the glass.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
