What are the conditions necessary for refraction?
Refraction occurs when light passes from one medium to another of different optical density. The speed of light must change as it travels from one medium to another at an angle, causing it to bend. The angle of incidence must also be different from the angle of refraction for refraction to occur.
What surfaces refract light?
For refraction to occur, there must obviously be two different substances that are both transparent to the radiation or waves under consideration. Also, the two substances must have different indices of refraction.
What are the 3 conditions that must be met for refraction to occur?
For refraction to occur, the light must be passing from one medium to another, the angle of incidence must be different between the two mediums, and the speed of light must change as it travels between the two mediums.
What are the conditions for total internal reflection to take place?
Light must travel from the optically denser medium to the optically less dense one. For total internal reflection to occur, the angle of incidence in the optically denser medium must be greater than the critical angle of that medium. The critical angle is that angle of incidence in the optically denser medium for which the angle of refraction is 90o.
How does reflection differ from refraction or defracion?
Reflection occurs when light bounces off a surface. Refraction is the bending of light as it passes through different mediums. Diffraction is the bending of light as it encounters an obstacle or aperture.
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 must light do in order to bend?
It must pass though a medium from an another medium.

What are the three conditions that must be met for refraction to occur?
For refraction to occur, the three conditions that must be met are: 1) The light must travel through different mediums with different optical densities, such as air and water. 2) The light must strike the boundary between the two mediums at an angle. 3) The light must not be incident perpendicular to the boundary.
Which is not a characteristic of imprinting?
the mother must be present. :))
What has to be different to allow refraction to occur?
Refraction occurs when light passes between materials of different optical densities, causing a change in its speed and direction. The change in speed must be coupled with a change in direction to enable refraction to occur.
Which is characteristic of a mineral?
It must be naturally occurring and crystalline.
If you have -2.75 eyesight what does it mean?
It means that -2.75 diopters of refraction must be interposed in front of your eye,and added to the refraction of your cornea plus your natural lens, in order to causeimages to focus on your eye's retina.
