The angle between an incident ray and the mirror is 30 degrees What is the angle of incidence? What is the angle of reflection? What is the total angle turned by the ray?

If the angle the ray makes with the mirror surface is 30 degrees, the angle of incidence (measured compared to the normal) is 60 degrees. The angle of reflection is equal to that, but is on the other side of the normal. Add them for the total angle turned.

thanks

Angle of reflection=30 degree

Total angle turned=60 degree

Not so good

To find the angle of incidence, angle of reflection, and the total angle turned by the ray, we need to know some basic principles of reflection.

1. Angle of incidence: The angle of incidence is the angle between the incident ray and the normal line drawn perpendicular to the surface of the mirror at the point of incidence.

2. Angle of reflection: The angle of reflection is the angle between the reflected ray and the same normal line.

3. Law of Reflection: According to the law of reflection, the angle of incidence is always equal to the angle of reflection.

Now, given that the angle between the incident ray and the mirror is 30 degrees, we can determine the angle of incidence, angle of reflection, and the total angle turned by the ray.

1. Angle of incidence: Since the angle between the incident ray and the mirror is given as 30 degrees, we can conclude that the angle of incidence is also 30 degrees.

2. Angle of reflection: According to the law of reflection, the angle of reflection is equal to the angle of incidence. Therefore, the angle of reflection is also 30 degrees.

3. Total angle turned by the ray: When a ray of light is reflected by a mirror, its direction changes by twice the angle of incidence or reflection. Thus, the total angle turned by the ray is 2 times the angle of incidence or reflection. In this case, the total angle turned by the ray is 2 * 30 degrees = 60 degrees.

To summarize:
- Angle of incidence: 30 degrees
- Angle of reflection: 30 degrees
- Total angle turned by the ray: 60 degrees
