What Factors Affect the Velocity of Light Projected by Lasers?

AI Thread Summary
The discussion centers on understanding what factors influence the velocity of light emitted by lasers. It emphasizes that light travels at a constant speed in a vacuum, but its speed can vary depending on the medium it passes through. Participants highlight the importance of considering the optical properties of different media, such as air, and how they may affect light speed relative to its wavelength. The color of the laser, such as red versus green, is also mentioned as a potential factor in this context. Overall, the conversation seeks clarity on the relationship between laser color, medium, and light velocity.

I am trying to find out, what is the affects the velocity of the light wave projected by the laser? I am going to ITT tech and this is a very diffucult thing to try and find on the web. I have been searching for over an hour trying to find the answer. I would really appreciate the help.

Light tends to travel at the speed of light particular to the medium it is traveling in.

Unless I've missed something, perhaps you need to rephrase your question?

Do you know what the difference is between, say, a red light wave, and a green light wave?

Yes you have. The speed of light is a constant in a vacuum.

What are the optical properties of air and how might they effect the speed of light as a function of wavelength ?

Sorry, mis-placed comma.
 
Thread 'Collision of a bullet on a rod-string system: query'

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'

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...
