It is given that the disispersive powers of crown and flint glasses are 0.06 and 0.10 respectively. Also the refractive indices for yellow light for these glasses are 1.517 and 1.621, respectively. We have to form an achromatic combination of prism of crown and flint glasses which can produce a deviation of `1^(@)` in the yellow ray. Evaluate the refracting angles of the two prisms needed.

Explanation

To solve the problem of forming an achromatic combination of prisms using crown and flint glasses that produces a deviation of 1 degree in the yellow ray, we will follow these steps:

### Step 1: Understand the Given Data
- Dispersive power of crown glass (w) = 0.06
- Dispersive power of flint glass (w') = 0.10
- Refractive index of crown glass for yellow light (μ_y) = 1.517
- Refractive index of flint glass for yellow light (μ_y') = 1.621
- Deviation (δ) = 1 degree
