Calculate Red Light Wavelength in Liquid | Angle of Refraction

AI Thread Summary
Red light enters a liquid from air at an angle of incidence of 39 degrees and an angle of refraction of 17 degrees. To calculate the wavelength of red light in the liquid, knowing its wavelength in air is 750 nm, the frequency remains constant during this transition. The discussion emphasizes the importance of clarity in post titles for better understanding and navigation. Additionally, there is a mention of a potential double post, suggesting that cross-posting may be more appropriate. The focus remains on the calculation of the wavelength and the implications of light behavior in different media.

Red light travels from air into liquid at an angle of incidence of 390 and an angle of reflection of 170. Calculate the wavelength of the red light in the liquid if its wavelength in air is 750 nm

can you give me some hint for this one too? :cry:
 
Physics news on Phys.org
The frequency does not change. Is this hint good enough?
 
double post...
 
Is it? I think the OP had posted another post with the title "another...", but the topic was different.

Dear rhxoehwhfh,

Please sacrifice originality for practicality and try to give your posts names dealing with the subject, for everybody's benefit.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged 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...
