WebThe indices of refraction for red, green, and violet light in glass are nred = 1.520, ngreen = 1.526, and nviolet = 1.538. When a ray of light passes through a transparent slab of glass, … WebThus, speed of light in glass is, v = 3 × 10 8 1.5 = 2 × 10 8 ms -1 (b) The speed of light in glass depends on the color of light. Since, the refractive index of the violet color is greater …

The refractive index of glass is 1.5. What is the speed of light in ...

WebThe frequency of red light is about 400 THz (and for violet is about 800 THz) Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy Blue light has higher … WebOne simple answer (and there are actual, deeper physics answers) is that the light interacts with the material, and those interactions are wavelength dependent. And, red light doesn't always travel faster than blue light - that is material dependent through those interactions … dexcom g6 tech support uk

25.28 What is the ratio of the speed of red light to violet light in ...

WebViolet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), … WebFor instance for some types of glass, the n value for frequencies of violet light is 1.53; and the n value for frequencies of red light is 1.51. The absorption and re-emission process causes the higher frequency (lower wavelength) violet light to travel slower through crown glass than the lower frequency (higher wavelength) red light. WebJul 18, 2024 · Red color travels fastest in crown glass as it has the largest wavelength ( 625 – 740). Blue travels at a speed lower than red. Violet travels with the least speed or … dexcom g6 thigh
