If equation of sound wave is y=0.0015 (62.8 x+316 t) , then its wavelength will be

Options

A0.2 unit
B0.3 unit
C0.1 unit
D2 unit.

Correct answer

C. 0.1 unit

Step-by-step solution

Equation of sound wave is y=0.0015 (62.4 x+316 t) . Standard equation of a sound wave is y=A 2 [ x + t T ] Comparing the given equation with the standard equation, we get 2 / =62.8 or, = 2 62.8 =0.1 unit. (where = wavelength of the wave)
