Answer:
A.NO, the position of stars asseen by us is not true. The starlight, on entering the earth's atmosphere, undergoes refraction continuously before it reaches the earth. ... Since the atmosphere bends starlight towards the normal, the apparent position of the star is slightly different from itsactual position.
B.Recombination of the seven colours of the dispersed white light toget white light is known asrecomposition of white light. Place a prism (P1) on a table and a screen behind it. ... Thus the second prism has recombined the dispersed light.
