What is the ratio of speed of sound in air when measured after laplace

1.	What is the ratio of speed of sound in air when measured after laplace correction to that measured by Newton’s formula?(a) 1.18(b) 0.84(c) 1.4(d) 0.71The question was asked during an internship interview.I need to ask this question from Speed of a Travelling Wave in portion Waves of Physics – Class 11
Answer» RIGHT answer is (a) 1.18 Explanation: By Newton’s FORMULA v = √(P/ρ) & after LAPLACE’s correction v = √(P/ρ), whereis ratio of specific heats of air. The ratio of speeds = √γ. For air γ = 7/5 & the ratio of speeds = √(7/5) = 1.18.
