Why does no refraction occur when the media have the same index of refraction?
Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.
What has to be different to allow refraction to occur?
The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
Does refraction occur only if rays are straight up and down?
No refraction can occur either way!
In which of the following would refraction occur?
More details!
In order for refraction to occur at least how many mediums are needed?
two. refraction is caused because of a wave passing between one medium to another, therefore changing its speed. Waves travel through different mediums at different speeds, depending on the medium's refractive index. By passing from one medium to another, it will change speed and therefore refract.

How does refraction occur in water?
It is because of the change in velocity of light in two different media.
At what angle does no refraction occur?
this angle is called the critical angle of a substance. To work it out you must know the refractive index of that substance.

No refraction can occur either way!
For refraction to occur in a wave the wave must?
For refraction to occur in a wave, the wave must enter a new medium at an angle.
What would occur if water were accidentally used in place of immersion oil?
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
Why refraction does not occur in opaque medium?
Refraction is the bending of the rays of light when it travels from one medium to another... For refraction to occur there should be some difference in the refractive index of the materials.... Refraction can also occur in Opaque medium........

Does refraction occur for both sound and light waves?
Refraction occurs for any waves, where there's a change in the medium.
What happens to speed of light from water to air?
It speeds up. Air and water are both media (plural form of medium). Each one of them has a different speed of light. As the incident ray passes from air to water, it refracts to be closer to the normal. A refraction occurs when there is a change in the speed of light. A change in the speed of light occurs when there is a change in media. In this case the media is changed from air to water. The second medium (water) must also have a lower speed of light in order for refraction to occur
