studied AS physics from this channel, and now studying A2 physics from here! you guys are literally the best teachers. so so so much love from your pakistani student !
Miss, if they give us a question saying, in a lab, emission spectral line is observed at a particular wavelength, and they also give us the wavelength of the same spectral line in the spectrum from a distant galaxy, which wavelength is our source wavelength to use in Doppler shift equation?

Congratulations to my both physics teachers for 10k subs on yt wohoo!!
Great lesson!
Great explanation
Thank you
when is the next video due?

Miss you have unlisted the cosmology playlist. Hence the fact that it has very small number of views. please make it public for all to see
