Refract
1.to bend light waves because of a change in media
2.the collision of two waves of the same frequency
3.a clear, solid body whose ends are equal and parallel triangles, and whose sides form rectangles
4.a line perpendicular to the surface of a medium that serves as a reference for light waves
5.a substance through which waves travel, such as glass or water
6. to alter the path or direction of something, such as sound or an opinion.
To refract means to bend light waves because of a change in media. This happens when light passes from one material to another, causing the light to change direction.
A clear, solid body whose ends are equal and parallel triangles, and whose sides form rectangles is called a prism. Prisms are often used to refract light and break it into its different colors, creating a rainbow effect.
A line perpendicular to the surface of a medium that serves as a reference for light waves is known as a normal. The angle at which light hits the surface is measured with respect to this normal line.
A substance through which waves travel, such as glass or water, is called a medium. When light passes through a medium, it can refract due to the difference in density or optical properties between the medium and the surrounding air.
