Problem 23P
(I) What is the speed of light in (a) ethyl alcohol, (b) lucite, (c) crown glass?
ANSWER:
Solution 23P:
As the light rays goes from one medium to another medium its speed change due to change in its wavelength on account of refraction.
Step 1 of 5
Concept:
Refraction: The phenomenon of bending of light as it passes obliquely from one transparent medium to another medium is called refraction of light.
Laws of Refraction:
The incident ray, the normal at the point of incidence and the refracted ray all lie in the same plane.
The ratio of velocity of light in first medium to the velocity of light in second medium is always constant for the two media and can be written mathematically as
Refractive index of the first medium
Refractive index of the second medium
Velocity of light in first medium
Velocity of light in second medium
