Question

The equation of the sound wave is y=0.0015 sin (62.8x +316t). Find the wavelength of this
wave :
(a) 0.2 unit (b) 0.1 unit
(c) 0.3 unit (d) cannot be calculated​

Answer 1

Answer:

b

Explanation:

62.8 x = k x

k = 2π / wavelength

62.8 = 2× 3.14 / wavelength

wavelength = 1/10 = 0.1 unit
