Why Fog Lights Are Yellow !!!!!!!!!!

Hello Friends, Welcome Back, Its been quite long time since I shared my last post here with you all. So here I am again with you to share my knowledge on one more question that arouse in my mind due to the intense cold wave that is going on in northern part of India. Yesterday was the most foggy day in my city and I was going to the school in my car with the fog lights of my car on and guiding me the way through the intense fog, and suddenly a question stroked in my mind, that why fog lights are yellow in colour although if we notice in the wavelength series that is VIBGYOR, red colour has the largest wavelength, then why we use yellow light insted of red light in fog lamps. As per my understanding it is important for fog lights to be one color (rather than white, which is all colors) because the different wavelengths(colors) of visible light scatter off the fog droplets differently. This phenomenon is known as "dispersion," because the different colors of light in...

Dinosaurs : Still In Between Us !!!!!!!!!!!!

Hello Friends, Welcome Back. I am back again with one another mysterious question of all times, "Do Dinosaurs Still Exists". The day I saw the movie "The Lost World", this question keep haunting me and kept me excited to find the answer for it and I researched a lot for the appropriate answer and what I conclude is I am going to share with you all. I hope I will be able to satisfy you all with my answer. Do dinosaurs still exist? The question may sound absurd. After all, conventional wisdom holds that these giant reptiles lapsed into extinction some 65 million years ago. Still, occasional reports from remote regions of the earth have kept the issue alive, if only to readers of tabloid newspapers and to the handful of scientists, adventurers, and nature writers who have tried to make sense of the accounts and, where possible, to investigate them. The idea of still-living dinosaurs has captured the public imagination for well over a century. Not only ...

The Beginning Of Our Vast Universe.........

Hello Friends, Welcome Back, Well today I am going to tell you about the history of our vast and endless universe. How did it came into existence. Well you all will be amazed to know that our this vast universe had started from a point as small as our skin pores. Now we are seeing so many galaxies separated by thousands of light years, humongous stars, planets and uncountable solar systems, but this all started from a single point as small as our skin pore. Science has advanced to the point where we can infer something about the entire universe. This has been a great challenge considering how unimaginably vast the universe is. The countless stars you see in the darkest sky constitute merely 3000 neighbors out of about 300,000,000,000 stars in our galaxy, and as many as 100,000,000,000 galaxies exist in the universe. Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the beginning of this past cent...
