A surveyor measures the distance across a straight river by the following method: Starting directly across from a tree on the op

posite bank, he walks x = 112 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is = 37.8°.

y = 11.3380m

<h3>What is Young's double-slit experiment?</h3>

The double-slit experiment is an experiment, that shows that light has both a wave nature or characteristic and a particle nature or characteristic, and that these natures are inseparable.

So, light is said to have wave–particle duality rather than be only a wave or only a particle. The same is true for electrons and other quantum particles.

According to the question,

The relative to angle θ, its adjacent side has length x and its opposite side is equal to width of the river, y;

tanθ = $\frac{y}{d}$ = y = dtanθ
