\nRefraction of light occurs when light passes from one transparent medium to another because the speed of light changes as it enters a different medium. This change in speed causes the light ray to bend at the interface between the two media.
\n<\/section>\n
\nThe change in the speed of light as it moves from one medium to another is the fundamental reason for refraction. The amount of bending is related to the refractive index of the media, which is defined based on the speed of light in the medium.
\n<\/section>\n
\nWhen light enters a denser medium (higher refractive index), its speed decreases, and it bends towards the normal. When it enters a rarer medium (lower refractive index), its speed increases, and it bends away from the normal. Option A is incorrect; while temperature can slightly affect the refractive index, it’s not the primary cause of the bending itself. Option B refers to amplitude, related to intensity, not direction. Option D is too vague; the speed change is the specific physical property responsible.
