SERCP$1113\mathrm{.}8.$OP$\mathrm{.}041.$

This figure shows a sinusoidal wave that is traveling from left to right, in the $+x-$direction. Assume that it is described by a frequency of $37\mathrm{.}0$ cycles per second, or hertz $($ Hz $).$

$($a$)$ What is the wave's amplitude $($in cm $)?$

$$ cm

$($b$)$ What is the wavelength $($in cm $)?$

$$ cm

$($c$)$ Calculate the wave's period $($in s$).$

$$

s

$($d$)$ Compute the speed of this wave $($in $\frac{m}{s}).$

$\frac{m}{s}$
