Question

red shift takes place when the apparent wavelength​

Answer 1

Dear Student,

◆ Answer -

Red shift takes place when the apparent wavelength​ is more than actual wavelength.

● Explanation -

When visible light from the source shifts towards red end of spectrum, it is called red shift. Here, apparent wavelength is more than actual wavelength of light.

When visible light from the source shifts towards blue end of spectrum, it is called blue shift. Here, apparent wavelength is less than actual wavelength of light.

Thanks dear. Hope this helps you...
