**Step 1: Understanding the Geometry and Applying the Law of Reflection** The mirror is on the floor, and the wall is vertical to the floor. The distance from the point where the laser hits the mirror to the wall is **a = 31.3 cm**. The reflected beam hits the wall at a height **b = 38.5 cm** above the mirror. By the law of reflection, the **angle of incidence** (θᵢ) equals the **angle of reflection** (θᵣ) with respect to the normal to the mirror’s surface. Here, the incident and reflected rays form a right triangle, with the base as **a** and the height as **b**. **Explanation:** The situation forms a right triangle where the point of incidence on the mirror is the vertex: - The horizontal distance from the mirror to the wall is **a**. - The vertical distance from the mirror to where the beam hits the wall is **b**. The angle of incidence θᵢ is the angle between the incident beam and the normal to the mirror. Since the mirror is flat on the floor, this is also the angle the reflected beam makes with the floor, heading up to the wall. --- **Step 2: Calculating the Angle of Incidence θᵢ** The tangent of the angle of incidence θᵢ in this setup is given by: \[ \tan \theta_i = \frac{b}{a} \] Substitute the given values: \[ \tan \theta_i = \frac{38.5}{31.3} \] \[ \tan \theta_i = 1.230 \] Now, solve for θᵢ: \[ \theta_i = \arctan(1.230) \] \[ \theta_i \approx 50.6^\circ \] **Explanation:** The ratio of the height (b) to the base (a) in the right triangle gives the tangent of the angle. Taking the arctangent provides the actual angle of incidence. --- **Final Answer Summary:** The angle of incidence θᵢ at which the laser beam strikes the mirror is **about 50.6°**.
