Why Does Glass Look Green at the Edge? - Get Help Now

Glass is Green?

when the glass is viewed at their edge , it looks green .





1.why it is green when viewed at the edge ?
2.Why its not green when we view other than the edge ?



i think polarization is the effect but if so,how does it take place .



please help me in this homework
thank u

It preferentially scatters this color when light goes through it, the same reason why the sky is blue. This means that glass absorbs and re-emits green light by preference. When the light is re-emitted it can be sent off in another direction - it is scattered in different directions and get caught up inside of the glass due to multiple absorptions and re-emissions. When one look at the glass sideways the amount of green light exiting the side will be more than that exiting a flat side due to the fact that more atoms are along the line of site when you look at the glass sideways.

I can provide some insight into why glass may appear green at the edge. This phenomenon is known as edge coloration and is caused by the way light interacts with glass at different angles. When light passes through a transparent material like glass, it can be refracted or bent in different directions depending on the angle at which it enters and exits the material.

In the case of glass, it is composed of a mixture of different elements such as silicon, sodium, calcium, and iron. The presence of iron oxide in the glass is what gives it a green tint. When light passes through the edge of the glass, it is refracted at a steeper angle, causing it to travel through a thicker portion of the glass. This thicker portion contains more iron oxide, resulting in a stronger green color.

On the other hand, when light passes through the center of the glass, it is refracted at a shallower angle and travels through a thinner portion of the glass, resulting in a weaker green color or no color at all.

As for why this phenomenon doesn't occur when viewing the glass from other angles, it is because the light is not passing through a significant enough thickness of the glass to cause a noticeable green color.

In terms of polarization, it is possible that the light passing through the edge of the glass is becoming polarized, meaning the light waves are all vibrating in the same direction. This can enhance the green color perception. However, further research is needed to fully understand the role of polarization in edge coloration.

I hope this helps with your homework. Remember, science is all about asking questions and seeking answers, so keep exploring and learning.
