WebThe refractive index for light going from glass to air will be: a) 1/3. b) 4/5. c) 4/6. d) 5/2. Answer: The correct answer is c) 1/3. Q22. The refractive indices of four media A, B, C, and D are 1.44, 1.52, 1.65, and 1.36 respectively. When light travelling in air is incident in these media at equal angles, the angle of refraction will be the ... WebGlass is denser than air, so a light ray passing from air into glass slows down. If the ray meets the boundary at an angle to the normal, it bends towards the normal. The reverse is also...
The speed of light in crown glass is 1.67*10^8. What the index of ...
WebIf the index of refraction of glass is 1.8 and the speed of light in air is 3.00 · 10^8 m/s, what is the speed of light in that glass? 1.67* 10^8 m/s As light shines from air to another medium, i = 30.0, the light bends toward the normal and refracts at 22.0. What is the index of refraction? 1.33 WebThe velocity of light in water and kerosene respectively is and . Which material has highest refractive index? Prove your answer by calculation?

WebApr 2, 2024 · The solution does indeed look wrong if everything you have supplied is correct. If the equation. v group = v phase − λ d v phase d λ. holds true, and. d v phase d λ > 0. then it is certainly true that. v phase > v group. where of course λ > 0. It is true (in general) that for dispersive mediums like glass, the group velocity is usually ... WebThe refractive index, represented by symbol n, is the velocity of light in vacuum divided by the velocity of light in a medium. The formula of the refractive index is as follows: n = c v. Where, n is the refractive index. c is the velocity of light in a vacuum ( 3 × 10 8 m/s) v is the velocity of light in a substance. WebVelocity of light in glass would be A 3×108 ms−1 B 2×108 ms−1 C 108 ms−1 D 1.33×108 ms−1 Solution The correct option is B 2×108 ms−1 F rom n= c v,v = c n= 3×108 (3 2) … chinook campers rv
