A ray of light travelling in air fall obliquely on the surface of a ca...
**Explanation:**
When a ray of light travels from one medium to another, it undergoes a change in its direction of propagation. This change in direction is known as refraction. The angle at which the ray of light strikes the surface of the second medium is called the angle of incidence, and the angle between the refracted ray and the normal to the surface is called the angle of refraction.
In this case, the ray of light is traveling in air and falls obliquely on the surface of a calm pond. The surface of the pond is the interface between air and water. So, the ray of light will undergo refraction as it enters the water.
**Law of Refraction:**
According to the law of refraction (Snell's law), the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for a given pair of media. This constant is known as the refractive index.
**Ray of Light from Air to Water:**
When light travels from air to water, it bends towards the normal. The angle of refraction is smaller than the angle of incidence. This means that the ray of light will deviate towards the normal as it enters the water.
**Answer: Deviate towards the normal (Option D)**
Therefore, the correct answer is option D - the ray of light will deviate towards the normal when it falls obliquely on the surface of the calm pond.
