it will become 45 degree
The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.
Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
Also 23 degrees.

The angle of incidence is ALWAYS equal to the angle of reflection, therefore the degree of the angle reflection is 55 degrees.
The angle of reflection is 40 degrees. The angle of incidence is equal to the angle of reflection.
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.
The key is to recognize that "the angle of INCIDENCE is equal to the angle of REFLECTION", for an 'Elastic' collision. So the answer is 20 degrees.
the angle of the ray of reflection is equal to the angle of the ray of incidence, in other word if a light wave hits glass at an angle of 30 degrees, the angle of reflection will also be 30 degrees
no a reflex angle is 145
Also 23 degrees.
