Absolutely. As a sidenote, always be sure to measure the angle from the normal.

### What are law of reflection?

1. The angle of incidence is equal to the angle of reflection. 2. The reflected ray, the incident ray and the normal at the point of incidence lie on the same plane.

### What is the angle of incidence of a ray if the reflected ray is at an angle of 90 to the incident ray?

The angle between the incident ray and reflected ray is known as angle of deviation due to reflection. This will always be equal to 2i. Here i is the angle of incidence. So if 2i = 90 then i = 90/2 = 45 So the angle of incidence has to be 45 deg

### When angle of incidence is equal to zero?

That happens when the incident ray is perpendicular to the surface at the point of incidence.

### How do angle of reflection and angle of incidence relate?

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The angle of incidence is equal to the angle of reflection because the light ray selects the shortest path to reach the destination. This behavior of light is known as Fermat’s principle.

### What is the angle of incidence if the angle of reflection is 15 degrees?

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.

### Does the angle of incidence equal the angle of reflection when a straight light ray hits a straight mirror?

Yes, the angle of incidence always equals the angle of reflection when a straight ray of light hits a mirror that isn't bent.

### What is the angle between the angle of incidence and the angle of reflection?

the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle

### Is there a fixed relationship between a incident ray and a reflected ray?

Yes. The angle of incidence and reflection are equal.

### State 2 laws of reflection?

The 2 laws of reflection are 1. angle of incidence is always equal to the angle of reflection. And 2. incident ray,reflected ray and the normal at the point of incidence lie in the same plane.

### The angle of incidence is the angle between the incident ray and the?

The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.

### Which angle is the angle of incidence?

The angle of incidence of a ray (or light or other electromagnetic radiation) to a surface is the angle between the incoming ray and the normal - which is perpendicular to the surface at the point of incidence

### How would you describe the angle of incidence?

In Physics, the angle of incidence is the angle a ray or beam of light makes meeting a surface. To visualize it, think of it as the angle a cricket ball, football, or basketball makes on hitting the ground. Also the angle of incidence is equal to the angle of reflection.
