Answer
amplitude = $1$
period = $240^o$ or $\frac{4}{3}\pi$
Work Step by Step
The gven graph shows one complete period of the sine function.
Since the highest point is equivalent to two squares from the x-axis, and each square representing 0.5, then the amplitude is:
$=2 \times 0.5
\\=1$
Horizontally, one period of the graph covers eight squares.
Since each square represents $30^o$ or $\frac{\pi}{6}$, then the period of the given function is:
$=30^o \times 8
\\=240^o$
or
$=\frac{\pi}{6} \times 8
\\=\frac{4}{3}\pi$
