Problem 91P
The index of refraction for red light in a certain liquid is 1.320; the index of refraction for violet light in the same liquid is 1.332. Find the dispersion (θV − θr)for red and violet light when both arc incident on the flat surface of the liquid at an angle of 45.00° to the normal.
ANSWER:
Solution 91P
Step 1 of 4
Here we need to find the dispersion for the red and violet light when both the arc incident on the flat surface of the liquid at an angle of
to the normal.
The refractive index of the red and violet light in the same liquid is given to be and
respectively. The refractive index of air is taken to be
.
Given data,
Incident angle,
Refractive index of the red light in liquid,
Refractive index of the violet light in liquid,
Refractive index of air ,
To find,
Dispersion
