amplitude = $1$ period = $240^o$ or $\frac{4}{3}\pi$
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 $=\frac{\pi}{6} \times 8 \\=\frac{4}{3}\pi$
