Final answer:
The question is about the law of reflection in Physics. It initially struck the mirror at an angle of 38°. After increasing the angle of incidence by 13°, the new angle of reflection is also 51°.
Step-by-step explanation:
The topic we are discussing here is the law of reflection in Physics, which states that the angle of incidence is always equal to the angle of reflection. The initial light from the laser was striking the mirror at an angle of 38° to the normal. When the laser is moved causing the angle of incidence to increase by 13°, the new angle of incidence will be 38° + 13° = 51°. Since the angle of incidence equals the angle of reflection, therefore, the new angle of reflection will also be 51°.
To determine the new angle of reflection, we can use the law of reflection, which states that the angle of incidence is equal to the angle of reflection. The laser is initially striking the mirror at an angle of 38° to the normal, so the angle of reflection is also 38°. When the angle of incidence increases by 13°, the new angle of incidence is 38° + 13° = 51°. Therefore, the new angle of reflection is also 51°.
