The dispersive powers of crown and flint glasses are 0.03 and 0.05 respectively, The refractive indices for yellow light for these glasses are 1.517 and 1.621 respectively. It is desired to from an achromatic combination of prisms of crown and flint glasses which can produce a deviation of `1^@` in the yellow ray. Find the refracting angles of the two prisms needed.

Explanation

To solve the problem of finding the refracting angles of the two prisms (crown and flint glasses) needed for an achromatic combination that produces a deviation of 1° in the yellow ray, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values:**
- Dispersive power of crown glass (\( \omega \)) = 0.03
- Dispersive power of flint glass (\( \omega' \)) = 0.05
- Refractive index of yellow light for crown glass (\( \mu_y \)) = 1.517
