5.6B & 5.6C Warm Up Mar25

Light traveling through the air moves in a straight line. An object viewed through water looks different because light rays that travel through water are –

• Bent

• Bounced

• Reflected

• Absorbed

Which of the following best models how light is reflected?

• An arrow hitting a target

• A ball bouncing off a wall

• An apple falling from a tree

• A marble rolling down a ramp

The diagram shows a periscope used to see objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope? The periscope –

• separates the light into different colors

• absorbs the light rays passing through it

• magnifies small objects so they can be seen

• contains mirrors that reflect the object

Students often use a hand lens to make small objects appear larger. A hand lens makes objects appear larger because the lens

• changes the color of the light

• bends light passing through it

• increases the light’s strength

• converts light energy to heat

Which of the following reflects light to produce an image?

• 
• 
• 
• 

Which of these best explains why a student can see her reflection in a computer monitor when the monitor is turned off?

• Black objects absorb most of the light striking them.

• The glass allows light to be transmitted through it.

• Smooth, shiny objects reflect a great amount of light.

• Computers produce light when they are being used.

A student sees a mirror image of a tree in a pond on a very still day. The student is able to see a mirror image of the tree in the pond because light striking the surface of the water –

• is absorbed.

• bends downward.

• becomes brighter.

• bounces off.

sunglasses and tinted windows

• refraction
• absorption
• reflection

Light hitting a prism is an example of

• Absorption
• Reflection
• Yellow Light
• Refraction

How does light travel?

• in a wavy path
• in a straight path
• in a zig zag path
