Why do we take vrms speed in de broglie wavelength not average speed for a gas
While solving many questions, I came across many solutions where we took v as vrms speed for de broglie wavelength of a gas but why can't we take v as average speed as it would give us average ...

What is the frequency of a standing wave? [closed]
I understand that constructive interference of waves results in standing waves. And for a wire with both ends fixed the frequency should match the fundamental frequency of the wire to produce standing ...

What is the mathematical support for the formula $f_n = n f_1$, used to calculate the frequency of a standing wave? [closed]
could someone explain to me the mathematical support for the formula $f_n = n f_1$. This formula refers to the fact that the frequency of a standing wave is equal to the number of antinodes times the ...

Understanding Loop Formation in a Plucked String
I have a question regarding the formation of loops when a string is plucked at different fractional lengths.
In a book I referenced, it is stated that plucking a string at 1/6 of its length produces 3 ...

How does flute work?
I started learning flute a few months ago. Here in India you can buy two types of flute hindustani and carnatic. Hindustani flute has a simple acoustics.
Lenth is inversely proportional to frequency.

Light waves can't have a wavelength
The wave nature of light comes from Maxwell's equations. More precisely, the two wave equations that come from them:
$$\Delta\vec{E}=\mu\varepsilon \frac{\partial^2\vec{E}}{\partial t^2}\\
\Delta\vec{...

Who wrote $c = λ ν$ for the first time and where can I find it?
I have been surfing for days and still I could not find who wrote the equation $c=λν$ for the first time. Neither I found a name for this equation. A lot about Planck's constant and energy related ...

Can anyone explain the relationship between the refractive index, the speed, wavelength and angle of a wave?
Can anyone explain the relationship between the refractive index, the speed, wavelength and angle of a wave?
in my book is states that $$n = \frac{v_1}{v_2} = \frac{\sin θ_1}{\sin θ_2} = \frac{λ_1}{...

Why do water surfaces have persistent "average wavelength" patches?
Have you ever stood above a river or lake and noticed that the surface has visible "patches"? It looks like the surface has different average wavelengths in some areas, leading to the light ...

How many 'wavelengths of length' can a wave have? [closed]
Since a wavelength, $\lambda$, is the length of a entire cycle
How many $\lambda$ (complete cycles) can a composed wave have? I mean, for $n \lambda$, how big can $n$ be? And what does it mean, ...

Why doesn't frequency change when the medium of the wave changes, and only depend on the source of the wave? [duplicate]
When the medium of the wave changes, the velocity and the wavelength does change, but not frequency, why?

Why Do Harmonic Components Define Wavelength in Diffraction and Interference Phenomena?
I'm exploring the physical principles underlying diffraction and interference, specifically how these phenomena depend on the wavelength of harmonic (sinusoidal) components of a wave. My question ...

Why does the equation of a wave contain the term $\omega t$ instead of $vt$ in the wave equation $y=A\sin (kx-\omega t)$?
Why does the equation of a wave contain the term $\omega t$ instead of $vt$ in the wave equation
$$y=A\sin (kx-\omega t).$$
I think of the constant $k$ which for higher values increases the frequency $...

$0$th overtone in closed organ pipes
I know about $1$st, $2$nd or other overtones in the formula of frequency in a one-sided open system (specifically in closed organ pipes) that is
$$ f = \frac{\left( 2 n + 1 \right) v}{4 L} \tag{1} \...
