Look at the diagram below. Ray 1 from the Sun moves through air and falls on the surface of a lake. Ray 2 is a ray which travels from the surface of the lake at the point Ray 1 strikes the lake, and moves towards air. Ray 1 and Ray 2 make the same angle with the surface of the lake. Ray 1 bends towards the vertical when it enters the lake as Ray 3

Which statement is true?

Ray 2 is the refracted ray.
Ray 3 is the reflected ray.
Ray 1 and Ray 2 make the same angle with the vertical line.
Ray 1 and Ray 3 make the same angle with the vertical line.

3rd statment

Explanation:

ray 1 and 2 are same vertical line

=>reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index. In the most general case, a certain fraction of the light is reflected from the interface, and the remainder is refracted.

increased stability in the completion of fluorine's outer shell.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
