All objects reflect or absorb the seven different colors of light. In the Colored Shadows activity, students use flashlights and colored cellophane to create shadows and explore the science of additive and subtractive colors of light. Transparent materials let most of the light pass through. Instead, it must be the case that they absorb all colors but one (just like a regular colored object), and that one color they partially transmit and partially reflect. When an object blocks part of the light, but lets part of the light through, it is called translucent. #2. thinhpham , glass (transparent surfaces) do not cast a shadow, nor a colored shadow at the moment.

Experimenting with Light Refraction, https://www.youtube.com/watch?v=Fql4TeeqYq8. Light actually slows down when it passes through other materials. Transparent and translucent objects still form shadows, but they may be faint, fuzzy or coloured. The only way I have found to get transparent objects to cast shadows it is to use PNG files (they have an embedded alpha channel - but I think Enscape reads it as a just a polar clear/solid rather than proper gradient: you also have to use a pointillism approach to shading.). Before clocks were invented, people used sundials to tell what time of the day it was. A shadow appears behind you! 0 0 Similar questions Transparent objects: Medium View solution The functionality to have glass shadows is definitely on our agenda and as hardware gets better and better I don't see a reason why we won't implement it in the future.
