NEET Physics Transverse & Longitudinal Waves MCQ Question
If a longitudinal wave travels through a medium with a bulk modulus of 2.5 x 10^9 N/m² and a density of 2500 kg/m³, what is the speed of the wave?
1000 m/s
500 m/s
1250 m/s
1414 m/s
Correct Answer
Detailed Explanation
The speed of a longitudinal wave in a medium is given by the formula v = √(B/ρ). Substituting B = 2.5 x 10^9 N/m² and ρ = 2500 kg/m³, we get v = √(2.5 x 10^9 / 2500) = 1000 m/s.
