Waves - Result Question 13

13. The equation of a wave is represented by: y=104sin[100tx10]. The velocity of the wave will be

[2001]

(a) 100m/s

(b) 250m/s

(c) 750m/s

(d) 1000m/s

Show Answer

Answer:

Correct Answer: 13. (d)

Solution:

(d) y=104sin[100tx10]

frequency, n=(1002π)sec1,λ=2π10m

velocity v=λn=(1002π)(2π×10)=1000m/s
