The image shows a number line between 0 and 1, with the arrow pointing to the second tick mark after 0. The line appears divided into four equal segments between 0 and 1. Each tick mark represents a fraction of 1, and since the arrow is pointing to the second mark, it corresponds to $\frac{2}{4}$, which simplifies to $\frac{1}{2}$.

Thus, the value the arrow points to on the number line is:

$\boxed{\frac{1}{2}}$
