Physics 62.1 Understanding Space, Time & Relativity (21 of 55) What is Relativistic z-Factor?

In this video I will re-calculate the frequency for the observer for the redshift of an RECEDING object (galaxy) using the z-factor for a RECEDING galaxy at v=0.866c.

Next video in this series can be seen at:

Please Add rest of videos..This playlist is so interesting and exciting..

Thanks again sir! It's a weird thing, this universe. Space and time, like yin and yang.

To solve these equation, I understand we can measure the observed light wavelength but how do we actually measure the speed at which the galaxy is moving? Thank you so much these videos. I have literally watched your channel the whole day today!

May we have the rest of the series please?

Hello, Does anyone know where the missing chapters are? Thanks.

[shashanksharma]

will there be more videos on this playlist

How would you calculate the observed frequency in this case and also in cases where two galaxies are moving relative to each other and you want the observed frequency
