MCQ
When a source of light is receding away from an observer, then the spectral lines will get displaced towards:
- AViolet region
- ✓Red region
- CUltra region
- DBlue region
✓
Answer
Correct option: B.
Red region
When an object moves away from us, its light waves are stretched into lower frequencies or longer wavelengths, and we say that the light is redshifted. It also explain the expanding nature of universe.
Shifting towards red end means wavelength is increasing.
