Question

a laser beam strikes a plane mirror reflecting surface with an angle of incidence of 43°. what is the angle between the incident ray and the reflected ray?a.) 43 b.) 45° c.) 86 d.) 90 e.) none of these

Answer 1

The angle between the incident ray and the reflected ray is 43°.

Step-by-step explanation:

When a laser beam strikes a plane mirror, the angle of incidence is equal to the angle of reflection. In this case, the angle of incidence is given as 43°. Therefore, the angle between the incident ray and the reflected ray is also 43°. So, the correct answer is option a.) 43°.

Answer 2

Answer: 86°

Step-by-step explanation:

The answer is 86° due to the angle of incidence equaling the angle of reflection. The angle of incidence is 43°, which is the measurement between the incident ray and the normal. The angle between the reflected ray and the normal is the angle of reflection, which is also 43°. So, both of these combined is 86°, the angle between the incident and reflected ray
