CP Ch13.3 Image Formation

What is a simple activity involving making a pinhole camera to observe upside-down images?

• Building a telescope

• Creating a kaleidoscope

• Constructing a periscope

• Making a pinhole camera

What did early cameras use for light admission, resulting in long exposure times?

• Lenses

• Mirrors

• Pinholes

• Filters

How can an image be formed through a pinhole?

• By reflecting light rays off an object

• By absorbing light rays from an object

• By diffusing light rays around an object

• By bending light rays towards an object

How do converging lenses, like in magnifying glasses, help in seeing small objects clearly?

• By making the objects appear larger

• By focusing light rays to form a clear image

• By reducing the size of the objects

• By distorting the shape of the objects

What can be an impressive demonstration of physics?

• Observing sunballs under sunlit trees

• Watching a movie

• Playing video games

• Reading a book

How can a converging lens create a brighter and clearer image?

• By dispersing light rays

• By blocking light rays

• By reflecting light rays

• By focusing light rays

What are natural pinholes called when sunlight passes through small openings in leaves?

• Sunspots

• Moonbeams

• Sunballs

• Starbursts
