State the laws of refraction of light.

Explanation:

Laws of refraction state that:

The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

i don't understand. explain it clearly

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
