Which of the following quenching medium is used for quenching of P/M parts?

Which of the following quenching medium is used for quenching of P/M parts? Correct Answer Oil

The typical quenching medium used for P/M parts include plain water, brine solution and oil. However, oil is the preferred medium since it avoids cracking (occurs due to drastic cooling) as well as corrosion.

Choose the correct relation for a combination of two prisms to be achromatic. (Where for the first prism: μv = refractive index of the medium in violet light, μr = refractive index of the medium in red light A = angle of the prism; For the second prism: μ′v = refractive index of the medium in violet light, μ′r = refractive index of the medium in red light, A’ = angle of prism.)
