Into the Abyss Lesson 1 Quiz M

Two students are using a flashlight and a mirror to test the properties of light, and how light interacts with a mirror. They develop a model to show three places they might look to observe the reflected light. From what angle should the students look to see the reflected light?

• a
• b

Kiara shines a flashlight on a mirror. Which arrow show the path the light would take when it reaches the mirror?

• Arrow B
• Arrow C
• Arrow D

Stanley looks at his pet fish in its fish tank. Why does Stanley see the fish in a different location to where it actually is?

• Light waves are poorly transmitted through water, causing objects to seem as though they are in different locations.
• Light waves bend (refract) as they pass from one medium (water) to another (air)
• Light waves are partially absorbed by water, causing their paths to bend.

Jo is sitting by a lake observing stars. She wants to develop a model that will help her explain why the starlight appears on the surface of the lake. What ideas should Jo include in her model to describe how the light interacts with the surface of the lake? Select all of the ideas about light that Jo should include in her model.

• Light transmits through the atmosphere
• Light reflects off the surface of the stars.
• Light reflects off the surface of the lake.
• Light transmits from the stars to the surface of the lake.

Jo wants to show how light travels from one place to another. How should Jo show light traveling between the stars and the lake in her model? Select the term that best complete this sentence: Jo should draw the light traveling in a ________ line.

• straight
• curve

A flashlight is used to produce a beam of light shining on a red pair of glasses as shown below. Which light wave property is being demonstrated.

• Reflection
• Absorption
• Refraction

Use the diagram below to explain how wavelength is related to the colors that we see: Different colors of light have different _________________________.

• wavelength
• amplitude

Use the diagram below to explain how wavelength is related to the colors that we see: When light is ___________________ from an object, its wavelength is what determines the color we see.

• absorbed
• reflected

Look at the picture below. Why is the light bending?

• When the light wave reaches the water, the frequency and wavelength change which causes the light to bend.
• When the light wave reaches the water, the amplitude and reflection of the wave changes which makes the light wave bend.

A flashlight is used to produce a beam of light shining on a lens as shown below. Which light wave property is being demonstrated.

• Reflection
• Absorption
• Refraction
