In which meduim is the wavelength of yellow light the shortest?
a. flint glass
b. crown glass
c. diamond
d. zircon

, i dont understand how to solve this at all

c. diamond has shortest wavelength.

Explanation:

Refractive index is inversely proportional to the wavelength.

n1.λ1=n2.λ2

Diamond: 2.419

Flint glass (pure): 1.60 - 1.62

Crown glass (pure): 1.50 - 1.54

Zircon: 2.15 - 2.18 .

Therefore, c. diamond has shortest wavelength.

a and b sometimes have a positive value

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
