Refraction, Color & Transparent Materials — Drills · Grade 6 Science
Chapter: Electricity, Magnetism & LightWhat these drills covers
By the end of Refraction, Color & Transparent Materials you should be able to:
- I can explain why light changes direction when it enters water or glass.
- I can explain why a submerged object appears shallower than it is.
- I can explain why a red object looks black under green light.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: refraction, spectrum, evidence, system boundary, uncertainty.
Problem 1
- A sample with missing measurements has proved those values are zero.
- Every ray must bend sideways at every transparent boundary.
- An object appears the same color under every possible light source.
- refraction: A change in light propagation speed at a medium boundary, commonly with oblique bending.
Answer and explanation
refraction: A change in light propagation speed at a medium boundary, commonly with oblique bending.
A change in light propagation speed at a medium boundary, commonly with oblique bending.
Problem 2
- spectrum: A range of light components distinguished by wavelength.
- An object appears the same color under every possible light source.
- Every ray must bend sideways at every transparent boundary.
- Repeating any method makes every causal claim true.
Answer and explanation
spectrum: A range of light components distinguished by wavelength.
A range of light components distinguished by wavelength.
Problem 3
Answer and explanation
No. It separates components of the incoming light through wavelength-dependent propagation.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
The surface cannot reflect an absent green component in this idealized model; observed color depends on both source and material.
