    Speed Waves
AI Thread Summary
In optically dense materials, electromagnetic waves, such as light, travel slower compared to their speed in a vacuum, while sound waves, being mechanical, generally travel faster in denser media. The speed of sound increases with the density of the medium due to its nature as a compression wave. Lower frequency waves tend to travel faster in optically dense materials, while higher frequency waves travel slower. This distinction highlights the differing behaviors of mechanical and electromagnetic waves in various media. Understanding these properties is crucial for applications in physics and engineering.

Hey Guys,

I was wondering which types of waves travel faster in optically dense materials and which waves travel slower in optically dense materials. Does light travel faster or slower and same with sound? Do all mechanical and electromagnetic waves follow these properties or does one follow one of the properties and the other one follows the other property?
Please answer these questions as soon as possible!
Thanks!

Light travels fastest when there is no medium (vacuum), so the less dense a material, the faster electromagnetic waves will travel. For sound waves, it is different, as sound requires a medium to travel through (as it is a compression wave) so as density increases, so does speed of sound waves through it. Sound is a mechanical wave, and all mechanical waves travel faster with density, to my knowledge.

the lower friquency wave travel faster in opticaly dens meterial higher friquency waves traval slower in optically denser media the light travels faster or slower and also same with sound
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
