A ray of light shines on a mirror. The angle between the incident ray and the mirror is 65 degree.
What is the total angle turned by the ray of light?
If mirror is level facing down
incoming ray is headed East 65 North which is 25 clockwise from North
outgoing ray is headed East 65 South which is 155 clockwise from North
turned from 25 to 155 which is 130 degrees
(which is 65 + 65 of course)
To find the total angle turned by the ray of light, you need to consider both the incident angle (angle between the incident ray and the mirror) and the reflected angle (angle between the reflected ray and the mirror).
In this case, the incident angle is given as 65 degrees. When a ray of light reflects from a mirror, the angle of incidence is equal to the angle of reflection. Therefore, the angle of reflection will also be 65 degrees.
To find the total angle turned by the ray of light, you can add the incident angle and the reflected angle:
Total angle = Incident angle + Reflected angle
Total angle = 65 degrees + 65 degrees
Total angle = 130 degrees
Therefore, the total angle turned by the ray of light is 130 degrees.
