The following sound waves have what velocity? (a) f = 36.3 hz, λ = 11.0 m m/s (b) f = 363.0 hz, λ = 4.80 m m/s (c) f = 3,630.0 hz, λ = 11.0 cm m/s (d) f = 36,300.0 hz, λ = 4.80 cm m/s

(a) v =  399.3 m/s, (b) v =  1742.4 m/s, (c) v =  399.3 m/s, (d) v = 1742.4 m/s

Explanation:

The velocity of a wave can be defined as:

  (1)

Where and f are the wavelength and frequency of the sound wave.

The values for each case will be replaced in equation (1).

(a) f = 36.3 Hz, λ = 11.0 m

But 1 Hz = s⁻¹, therefore:

So the sound wave has a velocity of 399.3 m/s.

(b) f = 363.0 Hz, λ = 4.80 m

So the sound wave has a velocity of 1742.4 m/s.

(c) f = 3,630.0 Hz, λ = 11.0 cm

Before using equation (1) it is necessary to express in meters.

⇒

So the sound wave has a velocity of 399.3 m/s.

(d) f = 36,300.0 Hz, λ = 4.80 cm

⇒

So the sound wave has a velocity of 1742.4 m/s.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
