Expert Answer:
Give f= 50 Hz
So ω = 2πf = 100π
Amplitude A = 0.5cm
Wavelength λ = v/f = 330/50 = 6.6 m = 66cm
Angular wavelength k = 2π/λ =2π/66
Putting the values in ideal eqaution of wave we get
y = 0.5 sin 2π(50t -- 
)

- Answer 23rd ques plz
- What is propagation constant (k)?
- Define longitudinal wave motion. What are the essential conditions required for the formation of longitudinal wave motion?
- Define transverse wave motion. What are the essential conditions required for the formation of transverse wave motion?
- A narrow sound pulse (for example, a short pip by a whistle) is sent across a medium. (i) Does the pulse have a definite (a) wavelength, (b) frequency, (c) speed of propagation? (ii) If the pulse rate is 1 after every 20s (i.e the whistle is blown for a split second after every 20s), is the frequency of the note produced by the whistle equal to 1/20 = 0.05 Hz?
