I HAVE.....no, a light wave travels in a straight path
WHO HAS....The definition for diffraction?

Back 5

I HAVE....it is seen as the "fuzziness" around shadows
WHO HAS....The definition for reflection?

Front 6

I HAVE....the bouncing of light off of a surface
WHO HAS....The definition of refraction?

Back 6

I HAVE....it is the bending of light as it passes from one material into another
WHO HAS....The definition for transmission?

Front 7

I HAVE....it is light passing through an object
WHO HAS....The definition for absorption?

Back 7

I HAVE....it is a small amount of light being taken in to the object it is passing through as heat energy
WHO HAS....What can light do as it travels in a straight path and hits an object?

Front 8

I HAVE....light can reflect, refract, transmit, or be absorbed
WHO HAS....What instrument can be used to refract white light?

Back 8

I HAVE....A prism
WHO HAS....What happens to white light as it travels through a prism?

Front 9

I HAVE.....different wavelengths are bent at different angles and are separated into the visible spectrum
WHO HAS....What are the colors of the visible spectrum?

Back 9

I HAVE....red, orange, yellow, green, blue, indigo, and violet
WHO HAS....Do the colors of the visible spectrum have the same wavelengths and travel at the same speed?

Front 10

I HAVE....no, colors of the visible spectrum have different wavelengths and travel at different speeds
WHO HAS....Why should you not wear dark-colored clothing on a sunny summer day?

Back 10

I HAVE....these dark-colored objects absorb lots of light as heat energy and become hot
WHO HAS....Why should you wear light-colored clothing on a sunny summer day?

Front 11

I HAVE....these colored objects reflect more light waves than they absorb and allow you to remain cool
WHO HAS....The definition for transparent?

Back 11

I HAVE....letting light through,objects can be clearly seen through this type of material
WHO HAS....The definition for translucent?

Front 12

I HAVE....is letting light through but scattering it, objects cannot be clearly seen through this type of material
WHO HAS....The definition for opaque?

Back 12

I HAVE.....this material does not let light through
WHO HAS....Is a window glass transparent, translucent, or opaque?

Front 13

I HAVE....transparent
WHO HAS....Is wax paper transparent, translucent, or opaque?

Back 13

I HAVE....translucent
WHO HAS....Are wood and iron transparent, translucent, or opaque?

Front 14

I HAVE....flashlights, lenses, prisms, kaleidoscopes, cameras, eyeglasses, refracting and reflecting telescopes, binoculars, microscopes, light boxes, spectroscopes, & mirrors use light
WHO HAS....How does light affect a camera?

Back 14

I HAVE....it is able to record images because the film is sensitive to light energy
WHO HAS....What is a wave?

Front 15

I HAVE....it is a disturbance that moves away from it starting point
WHO HAS....Can light waves travel through a vacuum such as space?

Back 15

I HAVE.....yes, light waves can travel through a space with no air
WHO HAS...The definition for wavelength?

Front 16

I HAVE....the distance from one crest of the wave to the next crest
WHO HAS....Which color of the visible spectrum has the shortest wavelength?

Back 16

I HAVE....VIOLET
WHO HAS....Which color of the visible spectrum has the longest wavelength?

Front 17

I HAVE....RED
WHO HAS...The definition for frequency?

Back 17

I HAVE....it is the number of waves produced each second
WHO HAS....What is the speed of light?

Front 18

I HAVE....300,000 kilometers per second or 186,000 miles per second
WHO HAS....What is the difference between a concave mirror and a convex mirror?

Back 18

I HAVE....concave mirrors curve inward at the middle, and a convex mirror curve outward at the middle
WHO HAS....Is a shaving or sometimes called a make-up mirror convex or concave?

Front 19

I HAVE....concave
WHO HAS....Are the side-view mirrors on cars and trucks convex or concave mirrors?

Back 19

I HAVE.... convex
WHO HAS....When sunlight passes through a prism, what do we call the collection of colors?

Front 20

I HAVE....the visible spectrum
WHO HAS....Is a lens transparent, translucent, or opaque?

Back 20

I HAVE.... transparent lens
WHO HAS....When objects create a shadow, are these objects allowing light to travel through or are they blocking the light?

Front 21

I HAVE....the objects are blocking the light
WHO HAS....Which color of clothing absorbs the most light rays or heat energy?

Back 21

I HAVE....black in color
WHO HAS....Why does a blue shirt appear blue?

Front 22

I HAVE....it appears blue because it absorbs all colors of light and reflects blue
WHO HAS....Which of the following celestial bodies are seen because of reflected light?

Back 22

I HAVE....the moon is seen because of reflected light. The stars and the sun send out light waves.
WHO HAS....What tool would you use to study samples of creek water in order to see organisms?

Front 23

I HAVE....a microscope
WHO HAS....What happens to light that is shone directly at a mirror?

Back 23

I HAVE....the light rays will be reflected back to the person holding the light
WHO HAS....Who used the first optical instrument, the telescope, to study the sky?

Front 24

I HAVE....Galileo
WHO HAS....What was Anton van Leewenhoek's job that helped him with using the first simple microscope?

Back 24

(end Westgate 5th grade unit on Light)

Front 25

I HAVE....opaque
WHO HAS....Are shadows created with transparent, translucent, or opaque objects?

Back 25

I HAVE....created with opaque objects since light will not pass through these objects
WHO HAS.... What are some tools that use the ability of light to reflect, refract, or transmit?
