3 - Class 12 - Physics - Wave Optics - Doppler Effect

In this video we have explained the Doppler Effect and it is defined as the apparent change in frequency of a wave, caused by the relative motion between the wave’s source and the observer. The Doppler Effect can be observed with any wave producing source. If we see at visible spectrum, we will find red light which has longer wavelength and blue light which has shorter wavelength. So, if any shift towards longer wavelength it is said to be as "red-shifts" and any shift towards shorter wavelengths is said to be as "blue shifts". The change in frequency is same as change in wavelength. Longer wavelength has lower frequency and shorter wavelength has higher frequency. As per Doppler Effect, when source moves towards us, it has high frequency with lower wavelength and then the shift is "Blue-shift". When source is away from us, it has lower frequency with higher wavelength and then the shift is "Red-shift". To view other chapter videos please purchase from our site https://www.scholarswing.in
