#منشور

تجزیه نور توسط منشور در ۶ نکته‌ی مختصر:

1. شکست نور:
هنگام ورود نور سفید به منشور، به دلیل تغییر سرعت نور در محیط‌های مختلف (هوا و شیشه)، نور می‌شکند.

2. پدیده‌ی پراکندگی (Dispersion):
نور سفید از رنگ‌های مختلفی با طول‌موج‌های متفاوت تشکیل شده که هرکدام به‌طور متفاوتی می‌شکنند.

3. شکست بیشتر برای طول‌موج کوتاه‌تر:
رنگ بنفش (با طول‌موج کوتاه‌تر) بیشتر از رنگ قرمز (با طول‌موج بلندتر) می‌شکند.

4. ایجاد طیف رنگی:
پس از عبور نور سفید از منشور، طیفی از رنگ‌ها (بنفش تا قرمز) تشکیل می‌شود؛ مانند رنگ‌های رنگین‌کمان.

5. منشور به عنوان جداکننده رنگ‌ها:
منشور با شکستن نور، رنگ‌های تشکیل‌دهنده نور سفید را از یکدیگر جدا می‌کند.

6. کاربرد در علم و فناوری:
این پدیده پایه‌ای برای ابزارهایی مانند طیف‌سنج، منشور اپتیکی و مطالعه‌ی ترکیب نور ستارگان است.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
