How are the wavelength and frequency of a sound wave related to its speed?

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...

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

(b) amplitude

Humming bees produce sound by vibrating their wings which is in the audible range. In case of pendulum the frequency is below 20 Hz which does not come in the...

Derivation of formula v = ν λ.  (i) 340 = 256 λ                        λ = 1.33 m.  (ii) 340 = ν (0.85)     ...

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...

Input frequency = 50 Hz For a half-wave rectifier, the output frequency is equal to the input frequency. Output frequency = 50 Hz For a full-wave rectifier, the output frequency is twice the...

(a) :- Frequency of full wave rectifier = 2 × input frequency = 2 × 50 = 100Hz.

(c) its wavelength decreases but frequency remains unchanged EXPLANATION:    When light is refracted into a medium its speed changes but the frequency remains the same because the energy associated with a...
