Explanation:

The angle of deviation of a prism refers to the amount by which a ray of light is refracted or bent when it passes through the prism. It is the difference between the angle of incidence and the angle of emergence.

The factor on which the angle of deviation of the prism does not depend is the angle of reflection (Option C). To understand why, let's briefly discuss the other factors:

1. Angle of incidence (Option A): The angle of incidence is the angle at which a ray of light approaches the surface of the prism. As the angle of incidence increases, the angle of deviation also increases. This is because a larger angle of incidence results in a larger amount of bending or refraction of the light ray.

2. Material of the prism (Option B): The angle of deviation is also influenced by the refractive index of the material of the prism. Different materials have different refractive indices, which determine how much the light ray is bent when it enters and exits the prism. A higher refractive index leads to a larger angle of deviation.

3. Wavelength of light used (Option D): The angle of deviation is also affected by the wavelength of light used. This is because different wavelengths of light have different refractive indices in a given material. This phenomenon is known as dispersion, and it causes the different colors of light to bend at different angles when passing through a prism.

However, the angle of deviation does not depend on the angle of reflection (Option C). The angle of reflection refers to the angle at which a ray of light is reflected from the surface of the prism. While the angle of reflection is important for determining the direction of the reflected ray, it does not directly influence the amount of bending or deviation that occurs within the prism.

In conclusion, the angle of deviation of a prism depends on the angle of incidence, the material of the prism, and the wavelength of light used. However, it does not depend on the angle of reflection.
