Description: In this Physics video for Class 12 in Hindi we explained what red shift is and how it can be explained using the Doppler effect of light. This is a topic of Chapter 10 - 'Wave Optics' from NCERT for Class 12. The Doppler effect or Doppler shift is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. 'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. 0:00 Introduction to Red shift 0:18 Dispersion and Spectrum 2:34 Spectral Line 3:57 Red shift in Spectral lines 6:12 Expanding universe 8:26 Doppler effect in Light ππππππ π·π³π¨ππ³π°πΊπ» ππππππ π΄ Click here to watch the whole playlist on Chapter 10 : 'Wave Optics' for Class 12 : youtube.com/watch?v=Sagr_3_lOKA&list=PLW0F47OesfFNwxeIPvGc7xBQg89Dvpjpj&index=1 ππππππ Related videos ππππππ π΄ Doppler Effect in Sound youtu.be/pyya2fRw48Y π΄ Relativistic Doppler Effect youtu.be/hQVT9HaJLsE ππππππ π·πππππππ π½ππ πππ ππππππ π΄ Wave Optics (Introduction) youtu.be/Sagr_3_lOKA π΄ Huygens Principle youtu.be/-iz3P4iuNaI π΄ Refraction using Huygens Principle youtu.be/UZhKHDT08Ow π΄ Reflection using Huygens Principle youtu.be/NeJRKrTRw6s
