The equation of a sound wave is `y=0.0015sin(62.4x+316t)` the wavelength of this wave is

Options

A. 0.2 unit
B. 0.3 unit
C. 0.1 unit
D. 2 unit

Answer

C

Explanation

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