The speed of light in air is 3 x 108 m/s. In medium X its speed is 2 x 108 m/s and in medium Y the speed of light is 2.5 x 108 m/s. Calculate:

(a) airnx = ?


(b) airny = ?


(c) any


Given:

Speed of light in air = 3.0x108m/s


Speed of light in medium X = 2.0x108m/s


Speed of light in medium Y = 2.50x108m/s


(c) airnx = ?



(d) airny = ?



(e) xny = ?
