1.	Speed of light in vacuum isA) 2 x 108 m/s B) 3 x 108 m/s C) 4 x 108 m/s 5 x 10 m/s
Answer» tion:Speed of LIGHT in AIR = 3.0 X 108m/sSpeed of light in medium X = 2.0 x 108m/sSpeed of light in medium Y = 2.50 x 108m/s(a) airnx = ?airnx = speed of light in air/speed of light in medium xairnx = 3.0 x 108 m/s/2.0 x 108m/s= 1.5(b) airny = ?airny = speed of light in air/speed of light in medium yairny = 3.0 x 108m/s/2.50 x 108m/s= 1.2(C) xny=?xny = speed of light in medium x/speed of light in medium yxny = 2.0 x 108m/s/2.50 x 108m/s= 0.8plz mark as brainlist
