Angle of Refraction: Find Low Power Laser Incident Angle

AI Thread Summary
A low power laser is incident at a 45-degree angle on the interface between crown glass and air, with crown glass having a refractive index of 1.52. The discussion revolves around calculating the angle of refraction using Snell's Law, n1sin(x1) = n2sin(x2). Participants highlight the need to determine the critical angle for crown glass to assess if total internal reflection occurs. If the angle of incidence exceeds the critical angle, no refracted ray will be produced. The conversation emphasizes the importance of correctly applying the formulas to avoid calculation errors.

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...
