Why is water transparent? पानी पारदर्शी क्यों है?


We can’t see through walls because electrons in the structure absorb visible light. Some light reflects off the wall, but no light gets through. Radio waves – the same stuff as visible light with a longer wavelength – go straight through. This is because electrons in a wall don’t absorb or reflect radio waves, due to their shape. Electrons in water act in a similar way to visible light so they don’t absorb or reflect most of the light. Instead they allow it to pass through relatively unimpeded, absorbing wavelengths like infrared and reflecting invisible UV.

हम दीवारों के माध्यम से नहीं देख सकते क्योंकि संरचना में इलेक्ट्रॉन दृश्यमान प्रकाश को अवशोषित करते हैं। कुछ प्रकाश दीवार से दूर दिखाई देते हैं, लेकिन कोई प्रकाश से नहीं गुजरता है। रेडियो तरंगें - एक समान तरंग दैर्ध्य के साथ दृश्यमान प्रकाश - सामान सीधे चलते हैं। इसका कारण यह है कि एक दीवार में इलेक्ट्रॉनों को उनके आकार के कारण, रेडियो तरंगों को अवशोषित या प्रतिबिंबित नहीं किया जाता है। पानी में इलेक्ट्रॉन दृश्यमान प्रकाश के समान कार्य करते हैं, इसलिए वे अधिकांश प्रकाश को अवशोषित या प्रतिबिंबित नहीं करते हैं। इसके बजाय वे इसे अपेक्षाकृत उन्मुक्त के माध्यम से पारित करने की अनुमति देते हैं, अवरक्त जैसी तरंग दैर्ध्य को अवशोषित करते हैं और अदृश्य यूवी को दर्शाते हैं।

CABLE MODEM IP Address Change

CABLE MODEM IP Address Change that way seemed alittle complicated and lenghty i pretty much do the same thing but this is how, and my isp, tmnet has never stopped me and ive changed my ip several times a day before 1. go to start/run and type in cmd 2. at the prompt type in ipconfig /all 3. write down your ip address, default gateway, and BOTH of your DNS servers 4. now here comes the troubleshooting part, this time at the prompt ping your ip with a number at the end changed Example: if your ip is 127.0.0.1 (haha) you would ping the new ip that you want to make sure it is not in use so it would look like this ping 127.0.0.2 if it comes up with request timed out 4 times then that ip is open and you can use it 5. go to control panel and then network connections 6. right click your active connection and go to properties 7. in the box in the new window highlight Internet Protocol TCP/IP (MAKE SURE THE CHECK MARK STAYS IN THE BOX!!!) 8. click on properties 9. after you fo...

Firefox Speed Tweaks

Yes, firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more? That's the beauty of this program being open source. Here's what you do: In the URL bar, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox. Note that these are what I’ve found to REALLY speed up my Firefox significantly - and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections - I mean with as much concurrent requests we’re going to open up with pipelining… lol… you’d better have a big connection. Double Click on the following settins and put in the numbers below - for the true / false booleans - they’ll change when you double click. Code: browser.tabs.showSingleWindowModePrefs – true network.http.max-connections – 48 network.http.max-connections-per-server – 16 network.http.max-persistent-connections-per-p...
