Consider the following:
(i) blue light of wavelength 450 nm, traveling through water
(ii) yellow light of wavelength 580 nm, traveling through air
(iii) red light of wavelength 670 nm, traveling through glass
a) Calculate the speeds of each color of light in their
respective mediums.
b) Rank from slowest-to-fastest these colors of light in their
respective mediums.
c) Rank from slowest-to-fastest these colors of light in vacuum.
In given problem Speed of color can be find using below formula
.
Where V= speed of color in medium
C= speed of color in Vacuum=3*108 m/s
All the colors travel with same speed (3*108 m/s) in Vacuum.
