Color Filters - Questions

The Color Filters Concept Builder is comprised of 42 questions. The questions are divided into 18 different question groups. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three different activities that can be engaged in through the Concept Builder. Those three activities are differentiated as follows:
 
  • Light Passage: Question Groups 1-6 ... Learners identify the light colors that pass through a color filter.
  • Color the Screen: Question Groups 7-12 ... Learners determine the color of a screen illuminated by light that passes through a filter.
  • Nmae That Filter: Question Groups 13-18 ... Learners use the appearance of a pattern of dots viewed through a filter to identify the filter type.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes. 

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions.
