I have one last question on the lab assignment regarding to Query #5.
I'm getting an incorrect expression when working with Einstein's equation to determine the perihelion of Mercury. At the end of the equation I'm getting a negative number within the radical of my 2nd pic near the end.
I...
Hi Mfb,
The equations were based off Newton's attempt to study Mercury's precession. And the point of the lab is to see why he was off in his calculations.
I'm wondering if the GM/r with with the gravitational constant G was used for the first attempt to calculate Mercury's precession by...
I was recently given a lab to work at home but I am having trouble understanding the formulas that they have used.

The Law's of reflection would state that θ_{1} = θ_{3}. I then got the angle as 60.1 degrees. I was looking at the picture incorrectly and used the wrong angles that were required for snell's Law. I got it now!
Thanks TSny!
Homework Statement
In the above figure, a ray of light is incident upon the interface between two media having indices of refraction n1 = 1.2 and n2, which is unknown. The known angles are f2 = 60° and f3 = 29.9°. (Note that the angles in the diagram may not be accurate.) What is the speed...
I was able to find another resource that was similar to my problem and was able to solve it by using snell's law under critical angle conditions:
n_{1}sinθ_{c} = n_{2}
and Snell's law under polarization conditions:
n_{1}sinθ_{p} = n_{2}cosθ_{p}
which simplified down to tanθ_{p} =...
Hi! Thanks for your guy's replies to my question. I was lucky to find out that I used the formulas incorrectly, and therefore, got the wrong answer. I was able to find the correct one and properly use it to get the right answer this time around. Thanks once again!
Homework Statement
The critical angle for total internal reflection for a substance is 58.0°. What is the polarizing angle for this substance?

Index of refraction: n = 1 / sin(θ_{c})
and n = tan (θ_{p})

Hi, Voko and lep11, thank you for your replies.
Okay, so I tried the wave speed of the EM-wave as 299,792,458 m/s and I figured that 2.4 seconds would be the total time that the EM-wave takes to go to the spaceship and back to mission control.
So to find the distance of the spaceship away from...

The Attempt at a Solution Since the main factor in the equation is the exponent that would be changing as n goes to infinity, I know that from the p series as p > 1 the the series converges. So I know...
