Hi Is the light from other stars has the same electromagnetic spectrum ?

Is time=distance traveled /speed , applicable to the light traveling through space ? or are there any other equations to apply to calculate the time of flight between different planets?

Hi Recently I have watched a video from The Hubble Telescope on You Tube . He says,light travels with the speed of light through the space for billions of light years to reach us from other planet . The images what we are seeing from the Hubble telescope are the past images of that particular...

Hi, I am also planning to build a telescope, need to collect all the equipment. looking for best measurements and its type.The suggested book was "How to make a telescope " Jean Texereau.

thanks for the textbooks reference but could not get the proper link to download . I agree, mounting would be more challenging than getting mirrors . Still on the way to decide which telescope, refractor : reflector ?

Hi I am very much interested to build a telescope on my own. I am looking for a complete guide to build a telescope and getting the apparatus needed ? Thank you in advance for all suggestions.

I would suggest you that while calculating derivative of an function if you see any constant in that equation ,you can substitute 0 directly which makes your equation simple. In your equations substitute 0 in place of dw/dt of your acceleration equation .

Hello everyone ! I have completed my postgraduation in physics without any projects from an indian university five years back .I think some universities may call it as masters by coursework Before and after completion of post graduation I had worked for 4 years in different colleges and...

Hi, A bit is a fundamental unit of information, classically represented as a 0 or 1 in your digital computer. I now number 100 is written in classical bits 0 and 1 as 1100100.Then How to represent 100 in qbits. cheers!

moment of inertia of a point mass with respect to an axis is the product of mass times the distance of the axis squared.So "r" is the distance of the mass "m" from the axis of roation.

Any force like u have mentioned comes under one of the four fundamental forces of nature . The force can be categorized Depending on the objects responsible in generating the force . Understanding the forces in simple terms ... The force that acts between two celestial bodies like...

Hi I am a postgraduate in physics from INDIA living in Australia . what type of opportunities I can get in Australia. cheers !

In my opinion , "all physics that is not quantum mechanics is classical mechanics" is not acceptable. The many microscopic problems that's were not explained correct by classical mechanics were successfully got solutions by taking quantum theory into consideration. And other branches like...

In case the quantum mechanics is applying in semiconductors ,transistors ,molecular geometries , can I say like this..."quantum mechanics is necessarily to be understand to study solid state physics and electronics."

vanhees71, What I meant by Real world is , there are many theories ,laws and principles are there in quantum mechanics .whenever I read any topic for example Linear harmonic oscillator , there equations mentioned for which some solutions are given .I could understand the...
