Answer
The black or shorter curve is $y=cos x$
The red or longer curve is $y=cos \frac{x}{3}$
Hence it is clear that shorter the value of B, longer will be the cycle of the curve.

The black or shorter curve is $y=cos x$
The red or longer curve is $y=cos \frac{x}{3}$
Hence it is clear that shorter the value of B, longer will be the cycle of the curve.
