اگر یك طرف طناب (یا فنری) ثابت شده باشد و شما طرف دیگر آن را به نوسان درآورید، آن گاه امواج به طور پیوسته به سمت نقطه ثابت حركت می ‌كنند و در حالی كه وارونه شده ‌اند، بازتاب می ‌كنند. در هنگامی كه شما به طور پیوسته در طول طناب موج ایجاد می ‌كنید، امواج تابیده و بازتابیده در دو جهت مختلف شروع به حركت می ‌كنند و در این اثناء با یكدیگر تداخل نیز می ‌كنند در فیلم زیر نحوه تشکیل امواج ایستاده در طناب نشان داده شده است.

[http://www.aparat.com/v/LyYvd]




امواج ایستاده

اگر طناب با بسامد مشخص به لرزش درآید دو موج تابیده و بازتابیده با یكدیگر تداخل می‌ كنند و بر اثر آن یك موج ایستاده با دامنه بزرگ حاصل می ‌شود.

امواج ایستاده


 
این موج از آن جهت ایستاده نامیده می ‌شود كه از ظاهر آن بر نمی‌آید كه در جهتی خاص حركت كند. در حقیقت در نقاطی كه طناب ساكن است دو موج با یكدیگر تداخل ویرانگر داشته ‌اند و بر اثر آن گره به ‌وجود آمده ‌است.

در مقابل، نقاطی كه طناب با حداكثر دامنه نوسان می ‌كند دو موج به صورت سازنده با یكدیگر تداخل نموده ‌اند و اصطلاحاً شكم حاصل شده ‌است.

Hey would you mind sharing which blog platform you're using?
I'm planning to start my own blog in the near future but I'm having a tough time selecting between BlogEngine/Wordpress/B2evolution and Drupal.
The reason I ask is because your design seems different then most
blogs and I'm looking for something completely unique.
P.S My apologies for getting off-topic but I had to ask!

I know this web site provides quality dependent content
and extra material, is there any other website which gives such information in quality?

The other day, while I was at work, my cousin stole my apple
ipad and tested to see if it can survive a twenty five foot drop, just so she can be a youtube sensation. My apple ipad is now broken and she has 83 views.
I know this is totally off topic but I had to share it with someone!

Admiring the persistence you put into your blog and in depth information you
offer. It's great to come across a blog every once in a while that isn't
the same old rehashed material. Wonderful read! I've bookmarked your site and I'm including
your RSS feeds to my Google account.

Hi! I just wanted to ask if you ever have any issues with hackers?
My last blog (wordpress) was hacked and I ended up losing a few months of hard work due to no back up.
Do you have any methods to protect against
hackers?

Nice post. I used to be checking constantly this blog and I am inspired!
Very useful information particularly the ultimate phase :) I maintain such info a lot.
I was seeking this particular information for a long time.

Thanks and best of luck.

Have you ever thought about including a little bit more than just your articles?
I mean, what you say is valuable and all. Nevertheless imagine if you
added some great graphics or video clips to give your posts more, "pop"!
Your content is excellent but with pics and videos,
this website could undeniably be one of the very best
in its field. Excellent blog!

Keep on working, great job!
دوشنبه 28 مرداد 1398 06:53 ب.ظ
Aw, this was a really good post. Taking a few minutes
and actual effort to make a really good article… but what can I say… I procrastinate a lot and never seem to
get nearly anything done.
دوشنبه 28 مرداد 1398 12:27 ق.ظ
I was wondering if you ever considered changing
the structure of your blog? Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content so
people could connect with it better. Youve got an awful
lot of text for only having one or 2 pictures. Maybe you could space it out better?

Hi! This post could not be written any better!
Reading through this post reminds me of my good old room mate!

He always kept talking about this. I will forward this article to him.

Pretty sure he will have a good read. Thanks for sharing!

This post offers clear idea designed for the new viewers of blogging,
that truly how to do running a blog.
پنجشنبه 3 مرداد 1398 10:35 ب.ظ
I've been surfing online greater than three hours today, but I by no means discovered any attention-grabbing article like yours.
It's lovely value enough for me. Personally, if all site owners and bloggers made
excellent content material as you probably did, the web will likely be much more helpful than ever before.

I read this piece of writing completely regarding the resemblance of newest and
previous technologies, it's awesome article.
دوشنبه 24 تیر 1398 10:52 ق.ظ
Good day! Do you know if they make any plugins to protect against
hackers? I'm kinda paranoid about losing everything I've worked hard on. Any tips?
سه شنبه 18 تیر 1398 09:47 ق.ظ
Hey are using Wordpress for your blog platform?
I'm new to the blog world but I'm trying to get started and create my own. Do you need any html coding knowledge to make your own blog?
Any help would be really appreciated!
شنبه 8 تیر 1398 04:07 ق.ظ
I have been surfing online more than 4 hours today, yet I never found any interesting article like yours.
It's pretty worth enough for me. In my opinion, if all
website owners and bloggers made good content as you did,
the net will be a lot more useful than ever before.
چهارشنبه 22 خرداد 1398 08:17 ب.ظ

I think this is among the most vital info for me. And i'm glad reading your article. But wanna remark on few general things, The website style is wonderful, the articles is really great : D. Good job, cheers
دوشنبه 20 خرداد 1398 02:19 ق.ظ
Incredible! This blog looks exactly like my old one!

It's on a completely different subject but it has pretty much the same page layout and design. Superb choice of colors!
شنبه 18 خرداد 1398 03:45 ب.ظ
I have been browsing on-line more than three hours
nowadays, yet I never found any attention-grabbing article like
yours. It's beautiful price sufficient for me. Personally, if all webmasters and bloggers made just right
content material as you did, the web will likely be a lot more useful than ever before.
دوشنبه 13 خرداد 1398 12:50 ب.ظ
I am really impressed with your writing skills and
also with the layout on your blog. Is this a paid theme or
did you customize it yourself? Anyway keep up
the nice quality writing, it's rare to see a great blog like this one these
days.
یکشنبه 12 خرداد 1398 05:16 ق.ظ
I don't know whether it's just me or if perhaps everybody else experiencing issues with your site.
It appears as if some of the text on your posts are running off the screen. Can someone else please
comment and let me know if this is happening to them as well?
This might be a issue with my browser because I've had this happen previously.

Thank you
