Question

you can construct a periscope with two parallel mirrors, as shown in the diagram. a ray of light enters from the object. it reflects off the first mirror and then the second mirror to the eye. use the diagram to answer the question. what is true about ∠1 and ∠2? explain. click the icon to view the law of reflection. using the you can show that ∠1 and ∠2 are

Explanation:

Step1: Recall law of reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Step2: Analyze angles in periscope

In a periscope with parallel mirrors, due to the parallel - nature of the mirrors and the law of reflection, the angle of incidence on the first mirror and the angle of reflection from the second mirror result in equal angles. Let the angle of incidence on the first mirror be related to ∠1 and the angle of reflection from the second mirror be related to ∠2. Since the mirrors are parallel, the normal lines to the mirrors are parallel. Using the law of reflection and properties of parallel lines (alternate - interior angles), we can show that ∠1 and ∠2 are equal.

Answer:

The law of reflection; equal
