  Why do our clothes appear darker when they get wet? Hi guys, I hope you all will be fine and enjoying. Today in this post we are going to know why do our clothes appear darker when they get wet. So, Let's start.... Any cloth is made from a yarn or fibre. That fibre in turn made of smaller micro-fibre. Some of the photons of light are absorbed but some are reflected and land on our retina and that gives us the sensation of seeing the cloth as having a certain level of brightness.  But when the cloth gets wet the water fills in the gaps between each individual microfiber or yarn. When light falls on the wet cloth, some of it is now more likely to enter the water and be bent away from our eyes. So, some of the light that would have previously been reflected off the cloth back to our eyes is now bent away. Fewer photons of light get back to our eyeball and so the wet cloth appears darker than the dry cloth. But as the water gradually evaporated more and more light is reflected back t

 Reasons Behind Numbers Written on Coaches of  Trains.

Hello guys,

I hope you all will be fine and enjoying.You might have noticed the numbers written on coaches of the train.Today in this blog I am going to make you understand reasons behind the numbers written on coaches of train as shown in following image:-



The first two numbers tells about the year of manufacture.The other three numbers tell about the serial number of train manufactured in that particular year.

Let's take an example to understand it clearly.



Here in this coach first two numbers 98  tells about the year in which it is manufactured which is 1998.And the last three numbers tells that it is 217th coach manufactured in 1998.

Here Is a Question for you

If 04053 is written on coach of train then what it's means?

ट्रेनों के कोच पर लिखे गए नंबरों के पीछे का कारण।
हैलो दोस्तों,
  मुझे उम्मीद है कि आप सभी ठीक होंगे और आनंद ले रहे होंगे। आपने ट्रेन के कोचों पर लिखे नंबरों पर गौर किया होगा। इस ब्लॉग में मैं आपको ट्रेन के डिब्बों पर लिखे गए नंबरों के पीछे के कारणों को समझने जा रहा हूँ, जैसा कि निम्नलिखित चित्र में दिखाया गया है: -
पहले दो नंबर निर्माण के वर्ष के बारे में बताते हैं। अन्य तीन नंबर उस विशेष वर्ष में निर्मित ट्रेन की क्रम संख्या के बारे में बताते हैं।
इसे स्पष्ट रूप से समझने के लिए एक उदाहरण लेते हैं:-
यहां इस कोच में पहले दो नंबर 98 उस वर्ष के बारे में बताते हैं जिसमें यह निर्मित होता है जो कि 1998 है। और अंतिम तीन नंबर बताता है कि यह 1998 में निर्मित 217 वां कोच है।
यहाँ आपके लिए एक प्रश्न है  
अगर ट्रेन के कोच पर 04053 लिखा है तो इसका क्या मतलब है? 
 अपना जवाब नीचे लिखें|

 धन्यवाद...
