Sound Wave Formula: Understanding the principles of sound waves is interesting, especially for those aiming for NEET 2025. Sound Wave Formula, a fundamental topic in the NEET 2025 syllabus develops an understanding of the concept.
Aspiring medical students preparing for NEET can benefit from a comprehensive exploration of sound wave formulas, ensuring a strong foundation for the upcoming examination.v = √(B/ρ)
where B is the bulk modulus of the medium and ρ is the density of the medium.v = fλ
This formula describes the relationship between the frequency, wavelength, and speed of a sound wave.I = (1/2)ρvA²ω²
where ω is the angular frequency of the sound wave.f' = (v ± vo)/(v ± vs) * f
where f' is the observed frequency, f is the source frequency, vo is the observer's velocity, and vs is the velocity of the source. Intensity Level (L) and Sound Level (β)L = 10 * log 10 (I/I0) β = L - 10 * log 10 (I 0 /I 1 )
where I 0 is the reference intensity and I1 is the actual intensity.y = A sin (ωt – kx)
L = 10 log 10 (I/I 0 ) dB
I 0 = the minimum intensity human ear can hear I = intensity at a distance r from the point sourcef’ = f (v-v 0 /v-v s )
Apparent wavelengthλ’ = λ (v-v s /v)
Understanding and applying these formulas is essential for solving problems related to sound waves in the NEET physics exam. If you want to explore and learn more about such formulas, you can join PW's NEET online coaching where a team of dedicated teachers personally mentors each candidate.
