As light hits a suspension of optically active substance, the light will hit one of the molecules. The light bounces off this molecule. It then hits another molecule, and bounces off this in the same direction. This keeps happening over and over again. The chirality of the molecule determines the direction and the size of the molecule determines how far it will be rotated.

What happens to a ray of light that slows down when it hits a new medium at an angle?

The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.


A ray of light travelling from medium A to medium B bends away from the Norman Which medium is optically denser?

Medium A is the more optically dense medium. As when the light enters B its speed increases taking it toward the normal.


Light waves will bend when passing from one transparent substance to another unless?

Refractive indexes of both the substances are same


Why does light appear bent?

Light exhibits wave characteristics. It is a characteristic of waves to travel in the direction of higher density. Light will bend towards the thicker parts of the glass. To be honest, there is no easy answer why that happens unless one wants to resort to quantum mechanics which is above the heads of most.White light is composed of a variety of frequencies. The wave rule is "longest is strongest" so the longest wave lengths are in the reds while the shortest wavelengths are in the blues. Blue will bend most and red the least. If light passes through a prism the beam will be spread out wider and the light will be bent towards the thicker part of the prism and the result will be a "rainbow" effect.Check out "index of refraction" You will see each will be different depending on what the material is. The angles change when light goes from one density to another. It's the same reason why you're pencil looks different when you put it in a glass of water.The light bends because as the light is entering the glass block it changes directon and slows down

When light rays enter a new medium at an angle what does the change in speed cause the ray to do?

The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.

What conditions will bend light?

This phenomenon is called diffraction. when light is incident on the opaque substances having width comparable to wavelength of light then light bend.


How is optical density related to refraction?

As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)

What is the difference between refractions and lens?

First lets consider a double convex lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are traveling parallel to the principal axis. Upon reaching the front face of the lens, each ray of light will refract towards the normal to the surface. At this boundary, the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in which it travels fast (less optically dense) into a medium in which it travels relatively slow (more optically dense), it will bend towards the normal line. This is the FST principle of refraction. This is shown for two incident rays on the diagram below. Once the light ray refracts across the boundary and enters the lens, it travels in a straight line until it reaches the back face of the lens. At this boundary, each ray of light will refract away from the normal to the surface. Since the light ray is passing from a medium in which it travels slow (more optically dense) to a medium in which it travels fast (less optically dense), it will bend away from the normal line; this is the SFA principle of refraction.

Which way will light bend when passiing from air to quartz?

The refractive index of air is about 1.0003, and of quartz about 1.45, so quartz is the more "optically dense" medium in this situation. When light goes from a less dense medium to a more dense medium, it is refracted toward the normal. The normal is the imaginary line perpendicular to the surface where the light enters.


Does light bend as it passes through materials?

Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
