Which of the two prisms, A made of crown glass and B made of flint glass, deviates a ray of light more?
Answer
For a given angle of incidence, the prism with a higher refractive index produces greater deviation than the prism which has a lower refractive index.
As refractive index of flint glass prism (B) is more than a crown glass prism (A) (i.e. μflint > μcrown)
Hence, a flint glass prism (B) produces more deviation than a crown glass prism (A).
