We know angle of incidence = angle of reflection. Hence, angle of incidence will be 24/2 = 12 degrees. (which is also angle of reflection)

The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.

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.

Also 23 degrees.

Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."

The angle of incidence is equal to the angle of reflection. Therefore, if the angle between the incident and reflected rays is 60 degrees, the angle of incidence is also 60 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.

When a ray of light is incident normally on a plane mirror, the angle between the incident ray and the reflected ray is 0 degrees. This means that the reflected ray will travel back along the same path as the incident ray, creating a symmetry in the reflection process.

The incident angle would also be 10 degrees since the angle of reflection is equal to the angle of incidence according to the law of reflection.

Call the angle from the incident ray to the normal X. The angle of the reflected ray to the normal also has to be X because the incidence angle and the reflected angle are equal by law of reflection. Since the angle between the reflected and incident ray is 90 degrees: 2*X = 90 So, X = 45 degrees.

The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.

The Law of Reflection states that the angle of incidence is equal to the angle of reflection. This means that when light or any other wave is reflected off a surface, the incident angle and the reflected angle are equal.

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.

The angle of incidence and reflection are measured with respect to the normal line, which is a line perpendicular to the surface at the point of incidence. The angle of incidence is measured between the incident ray and the normal line, while the angle of reflection is measured between the reflected ray and the normal line. Both angles are typically measured in degrees.

The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.

When light is incident on a surface at 30 degrees and the reflected and refracted rays are perpendicular, it means the angles of reflection and refraction add up to 90 degrees (since they are complementary angles). Therefore, the angle of refraction can be calculated as 60 degrees by subtracting the incident angle from 90 degrees. This is based on the principle of Snell's Law, which states that the angle of incidence and angle of refraction are related through the refractive indices of the two mediums.
