A ray of light travelling in air enters obliquely into water. Does the light ray bend towards the normal or away from the normal? Why? Solution. The ray of light bends towards the normal. When a ray of light enters from an optically rarer medium (having low refractive index) to an optically denser medium (having high refractive index), its speed slows down and it bends towards the normal. Since water is optically denser than air, a ray of light entering from air into water will bend towards the normal. Question. 2. Light enters from air to glass having refractive index 1.50. What is the speed of light in the glass? The speed of light in vacuum is 3 × 108 m s–1 . Solution. Refractive index of a medium, nm = Speed of light in vacuum/Speed of light in medium Speed of light in vacuum, c = 3 x 108 ms-1 Refractive index of glass, ng = 1.50 Speed of light in the glass, v = Speed of light in vacuum/Refractive index of glass = c/ng = 3 x 108/ 1.50 = 2 x 108 ms-1 light reflection and refraction class 10 exercise answers ncert class 10 science chapter 10 exercise solutions light reflection and refraction class 10 questions and answers pdf light reflection and refraction class 10 important questions with answers class 10 light reflection and refraction pdf class 10 physics chapter 1 light reflection and refraction notes ncert class 10 science chapter 10 pdf light chapter of class 10 notes pdf #class10light #lightreflection #combination #class10physics #class10science #magnetbrains Disclaimer: "This video is for educational and informational purposes only and is not intended to infringe on any copyrights.
