Refraction is the change in direction of a wave due to a change in its speed. It is essentially a surface phenomenon . The phenomenon is mainly in governance to the law of conservation of energy and momentum. The proper explanation would be that due to change of medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth. Refraction is described by Snell's law, which states that for a given pair of media and a wave with a single frequency, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equivalent to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the opposite ratio of the indices of refraction (n2 / n1):
You watch your hands and walked away
But I lost you and I found no haze
You left with heaven, stay with me
That time special change in green
And you say
I never quit have no
I alwayse here but ain't belong
If rainbow treat you on
To find that part of gold
If I could lay a picture in the colorblind of my soul
I drive what time will last
Like I was kind of bless
We wander if that change of colorblind to feel great it works
Uuh, uuh uuh, uuh,
If rainbow treat you on
To find that part of gold
If I could lay a picture in the colorblind of my soul
To find that part of gold
If I could lay a picture in the colorblind of my soul
I drive what time will last
Like I was kind of bless
We wander if that change of colorblind to feel great it works
