Establish the relationship between speed of sound, its wavelength and frequency. If velocity of sound in air is 340 m s–1, calculate

Yes, It is best described by Doppler Effect.

Wavelength: The distances between two consecutive compressions or rarefaction of a wave. Its S.I unit is meter.  Frequency: One compression and one rarefaction constitutes one vibration. The number of vibration in...

Speed = Wavelength x frequency  V = λ × ν

f = 220 Hz, V = 440 m/s  λ = f = 440 /220 = 2 m

Let AB = x, So t 1=x /30, and t2 =  x /20  Total time = t1 + t2 = 5x / 60  h.    Average speed for entire journeyTotal distance /Total...

Adolph Hitler became the Chancellor of Germany in 1933. He passed many laws to gain total control over his people. The Fire Decree was passed on 28th February, 1933.   The...

(b) varying velocity without having varying speed (d) nonzero acceleration without having varying speed. Explanation: Velocity and acceleration are vector quantities that can be changed by changing direction only (keeping magnitude constant).

(d) cannot be compared with its value in water. EXPLANATION:  The velocity of sound in a fluid is given as V =√(B/ρ) where B is the bulk modulus and ρ is the...

(e) x + y = 23 and  xy = 126 Now x2 + y2 = (x + y)2 – 2xy (23)2 – 2 × 126 529 – 252 x2 + y2 = 277
