Lecture - 9 Electromagnetic waves - I

nice one



[legomyeggo123]

i thought u never know where a particle is according to the heisenberg uncertainty principle...

[conductance99]

sir, you really are a life saver... ! :)

[GingleGangle1]

Is this in an university?

[davydany]

@GingleGangle1 IIT is India's version of MIT. If you graduate from IIT, you're considered to be one of the top most engineers in the world. Its a very prestigious institute.

@davydany of course

its maxwell not maxwells. idiot

The fringes will ONLY appear if the source is coherent, such as from the spatially coherent Sun, or coherent in time and space like a laser. A flashlight would not show the fringes.

Time is a scalar, and x, y, z are vectors. A particle exists at a point in spacetime (t, x, y, z). A collection of coherent particles can then have a pattern in spacetime. Incoherent particles have no such pattern.

[MCHelium]

x,y and z are scalar, too. only (x,y,z) is a vector ;)

[sweetser]

What one can do is write these with their basis vectors: (t e_0, x e_1, y e_2, z e_3), so that t, x, y, and z are scalars as you say. The combination of x e_1 does behave like a vector. While the norm of the basis vectors is 1 in flat spacetime, they can be greater or less than 1 in curved spacetime.

[gunshin2]

no (x,y,z) is a co-ordinate, [x,y,z] is a vector.. nub

[13houses]

man, i was wanting to learn about waves, i have no idea what a 'vave' is or how it pertains to waves.

[Nes232]

i was wanting?

[13houses]

yes, at the time.

[rockerfrog25]

hah

[Hambidosvinet]

too long clip just show me a link for a emp small bomb device for god sake :)
