A monochromatic ray of light travels from one optical medium P of absolute refractive index 2 to another optical medium Q of absolute refractive index 3. Compare the wavelength of light in P and Q |
|
Answer» When a monochromatic ray of light travels from a MEDIUM of refractive index N 1
to a medium of refractive index n 2
(n 2
>n 1
), SPEED decreases by a factor of n 1
n 2
. Because n 1
(optically RARER medium) on entering denser medium speed decreases. |
