Solving for Refractive Index: Light Beam Incident on Glass Slide

AI Thread Summary
The discussion centers on calculating the refractive index of glass when a light beam strikes it at a 60° angle, resulting in both reflection and refraction. The relevant equation used is Snell's Law, expressed as n1sinσ1 = n2sinσ2. The angles of incidence and refraction are identified as σ1 = 60° and σ2 = 30°, respectively. The calculation method presented, sinσ1 / sinσ2 = n, is confirmed to be correct. This approach effectively determines the refractive index of glass.

Homework Statement



A light beam incident on a glass slide at an angle of 60 ˚, being partly reflected and partly refracted. It notes that reflected and refracted beams are each at 90 ˚ What is the refractive index of glass?

Homework Equations



n1sinσ1 = n2sinσ2

The Attempt at a Solution



σ1 = 60°
σ2 = 30°

sinσ1 / sinσ2 = n

So, is this right?

Yes, it looks fine.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
