Why do light bulbs don't produce coherent waves? [duplicate]
My textbook says that light ways produced by light bulbs are not coherent but it doesn't describe the reason.
I was wondering how could two waves not be coherent regardless of the source they are ...

Michelson interferometer: beam splitter affects amplituedes?
Let's suppose an initial plane wave $\vec{E}=\vec{E_0}e^{i(\vec{k}\cdot\vec{r}-\omega t)}$ enters a Michelson interferometer . Let $\vec{E_1}=\vec{E_{01}}e^{i(kz-\omega t)}$ and $\vec{E_2}=\vec{E_{02}}...

How do EM waves interact with one another?
How is it possible to the interactions of EM waves with each other. E.G. how do visible waves interact with another wave frequency like X-Rays?

What is the physical significance of crest and trough in an electromagnetic wave?
Lets say an electron is vibrating at its mean position. From what I've gathered a crest would be its motion in one direction and a trough would be its motion in another direction. So first of all is ...

Destructive interference of electromagnetic waves
So EM waves can have constructive interference and destructive interference right?
If two strips of EM wave intersect at a point in a destructive manner, would their propagation terminate?
If yes, ...

In double-slit experiment, if one directs coherent light from two sources into each slit separetely, is ridges pattern expected to be seen?
I've read several QA here:
Is coherent light required for interference in Young's double slit experiment?
Why can't we duplicate the double slit experiment with two parrallel sources of light.....

Wave Interference, question on diagram
I'm trying to understand the wave behavior of light and have questions on diagrams of it. Wiki shows the following two diagrams from Christian Huygens describing the wave nature of light. I have ...

Do perpendicularly polarized waves interfere?
In the MIT ME optics OCW slides, it is written that parallel polarized waves do interfere but perpendicularly polarized waves do not interfere. However, isn't circular polarization formed by the ...

Why doesn't incoherent light cancel itself out?
What is the precise mathematical description of an incoherent single-frequency signal for any type of wave? The reason I'm asking is because of the following apparent paradox in which incoherent light ...

Imaging aberration
Qs: Doesn't a curved side lens produce less aberration than a flat lens in general because the overall angle of deviation is smaller in the curved lens?
Consider the following experimental results ...

Constructive interference of light waves: Formula give $4x$ the intensity instead of $2x$
For constructive interference, I look at two of the same phase shift. They may arise form a thin interference layer of $\lambda/2$ thickness.
The result of the E component should be double the ...

Waves interference in terms of fields and intensity
let's suppose that two electromagnetic waves (let's focus for instance on their electric fields) with same amplitude A and frequency, but with a difference $\Delta\Phi$:
$$E_{1}=A\cdot \sin\left(kz-\...

Do we take into account the physical angle between Electric fields and Magnetic fields during interference of light?
I have been studying interference of light waves for a while now and I have a doubt.
I have never seen any sources (books, internet , teachers) ever take into consideration about the "actual"...
