Wavefront | What is wavefront and its types?
Вставка
- Опубліковано 1 тра 2017
- A wavefront is a surface over which an optical wave has a constant phase. For example, When a stone is dropped in a still water, waves spread out along the surface of water in all directions with same velocity. Every particle on the surface vibrates. Such a surface which envelopes the particles that are in the same state of vibration is known as a wave front.
The wave front at any instant is defined as the locus of all the particles of the medium which are in the same state of vibration.
A point source of light at a finite distance in an isotropic medium
(Isotropic medium is the medium in which the light travels with same speed in all directions.) emits a spherical wave front.
A point source of light in an isotropic medium at infinite distance will give rise to plane wavefront.
A linear source of light such as a slit illuminated by a lamp, will give
rise to cylindrical wavefront.

Thanks for such a good explanation!
Thank you for this video it helps to study clearly
Thank you, explaining wavefronts is very valuable.
Too good and clear.
Thank u it is Really useful
Nice video thanks
this vedio really clarifies my doubt...thanks
great spelling
@@mrunalbhandare4899 😂😂😂😂😂
Video...!
point source will emit both the wavefronts :plane and spherical?
TASSO YAKA only spherial.....
@@richachauhan9442 Plane if the point source is located at infinity. Like the light rays from the sun
@@francisluwang4520 true if it have large distance then point source will create plane waves
jizakALlAH u khaira
What if all this happened because space is finite and time is infinite.
good explanation
Thank u ☀️
Thank you
Thank you v much mam
tqsm mam
What is phase plzzzzz......... . Answer...
What about elliptical wavefront....
First time I ..saw this video
Thanks mam
Super class
The only point which cannot be understood by just reading hc verma
yeaa i was looking for a 3d depiction of it
thanku.
Thank you so much ma'am 😊
❤
Is wavefront and wave same thing
Waves are made by wavefronts
@@LYNX-nz6rx Your answer is way too vague, as is the question.
Ok 🙏🙇
Love 💜💜💜
H C Verma line by line copied
wow nice video 👍👍👍
Plane wave front
Pls in chemistry
Here what is envelope ?
encompasses
Very nice explanation
👍👍
definitions are easy . thanks mam
its clear
thank u for this video.....
Thanku mam
Blink
👍🏻
i really didnt get that cylindrical wavefront part
take example of a tube light in which light spreads in a cylinderical manner
Ok
"Vibrating in phase " What's means of this.
state of oscillation basically
Superrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr4rrrrrrrrrrrrrrrŕrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr......................
I need in brief
Thx babe
lol
who is she your girl friend? Mind your language
Cuz of this ppl india is unsafe
Gaurav Gaikwad ......u r absolutely ryt
@@gauravgaikwad889 the whole world tbh, not only india
Thoda jayda time do
Thanks madam 😊😊
@@alishatariq5605 wtf are you on about?
Compared to all other people who an speak english, the indian-english dialect is the funniest im serious xD
It sounds gross
😆true
It's ncert explanation
literally just repeated the ncert lines.wow.
Suprrr.r.r.r..r
Hindi medium m de
Then what will we South Indians do?
Poda pundee
Bakwash
Waste of time
Tmko kuch aata hi nhi h
Thank you
Thanks mam
