This assessment was created as a portion of an SNHU course. It was intended to provide student choice with regard to DOK and item type to master the concepts of refraction.
Answer at least 1 question from each category. To demonstrate mastery of content, a total of 10 points is required. You may be asked to complete additional tasks (or questions) if less than 10 points are earned.
Question 1
1.
Category 1
Explain why light "bends" as it reaches a surface between different transparent materials.
Question 2
2.
Category 1
The more optically dense the material, the __________ the refractive index. Therefore air will have a __________ index of refraction than glass.
Question 3
3.
Question 4
4.
Question 5
5.
Category 2
Explain how a prism can produce the colors of the rainbow from white light. You may use a drawing to support your answer.
Question 6
6.
Question 7
7.
Category 1
Which of these correctly describes why light bends as it goes from air to water?
Light travels at the same speed through all types of matter.
Light doesn't bend, but our eyes change the image from reality.
Light travels at different speeds through different types of matter.
Category 1
Which angle in the image shows the angle of refraction?
A
B
Category 2
White light is shined (in air) through several glass objects.
Select the object(s) that will cause the light to separate into the colors of the rainbow.
A
B
C
D
E
F
Category 2
Which of these best explains why white light shined through some glass objects causes more colors to appear on the other side?
Light refracts in all glass objects and separates white light according to wave length, which results in visible separation of colors.
Light reflects when it hits the surface of objects and bounces off the molecules in the air.
Light reflects inside the object and the wavelengths change slightly.
Light refracts at different angles as it passes through objects. Objects with specific shapes cause light to separate into different colors.
