The refractive index of water is 1.333. Refractive index n = c/v where c is phase velocity of a wave in a vacuum and v is the phase velocity of the wave in the medium. If precision is needed, then more variables come into play and n will change slightly. The temperature of the medium, the frequency of the light, etc... all can come into play.
A good place to see pictures of light refraction is on Google Images or science websites such as National Geographic or ScienceDaily. You can search for "light refraction" or "photos of light refraction" to find a variety of images showcasing this phenomenon.
The word is rainbow. Rainbows occur when light is reflected inside droplets of water and then refracted out into the air.
Light travels in straight lines on earth, so you can change its angle by refraction but not curve it. However over interstellar distances it has been observed that light is bent by gravitation.
No, refraction occurs because light changes speed when passing from one medium to another. The change in speed causes the light wave to bend, resulting in refraction. If light did not change speed, refraction would not occur.
The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
What is Refraction?? What is Refraction??
light undergoes refraction when the matter changes the speed of light
Refraction of light allows for the change of appearance of an object
refraction
Reflection of light is the bending of light from its point. while refraction is the diverging of light from its bearing.
No a rainbow is the refraction of light through rain and is only an optical illusion
Refraction or Refraction of light is the scientific name for the bending of light. Same Thing.
The process of light bending as it enters a different medium is known as refraction. Refraction occurs because light changes speed when it travels from one medium to another, causing the light wave to bend.

In reflection the light bounces bach; in refraction the light passes through, but is bent at the interface.
The scientific term for the bending of light is refraction. Refraction occurs when light changes speed as it passes through different mediums, causing it to bend.
Because of refraction in the earth's atmosphere: The air density in the earth's atmosphere and therefore also the index of refraction of the earth's atmosphere decrease with increasing altitude. Snellius' law of refraction tells us that light is refracted towards the medium with higher index of refraction. Therefore, the light coming from any star that is not situated directly above the observer takes a curved path bent down towards the observer, arriving at the observer at a steeper angle than had it travelled on a straight line.
