When a ray of light passes through a boundary between two transparent media, it changes direction. What is this phenomenon known as?a. reflection. b. refraction.
c. interference.
d. diffraction.
e. dispersion.

The phenomenon is known as refraction. The correct option is B

Explanation:

Refraction is defined as the property of a change in the direction of light, when it passed from one medium to another. In the process of refraction, the direction to which the rsy of light follows changes as well as the velocity, but the frequency remains the same along the line of propagation.

The extent of propagation is determined by the nature of the medium allowing the propagation.If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. This effect also o view with mediums such as water.

The reason why the light rays bends away from its normal direction is that light slows down when it passes from the less dense air into the denser glass or water.

Other properties of light includes:

--> light travels in a straight line

--> light can be reflected

--> light can be diffracted

--> light can be polarized

explanation:

newton's third law, for every action there is an equal and opposite reaction.
