Sound and Light
| Question | Answer |
|---|---|
| What part of the electromagnetic spectrum can we see? | visible light |
| White light splits into | the full spectrum of colors. |
| What order does the spectrum of color follow? | ROYGBIV |
| Light entering a glass of water bends or | refracts |
| When light bounces off an opaque surface it is reflecting or refracting? | reflecting |
| When we see a red object we are really seeing ... | red being reflected back into our eyes |
| When all the colors are absorbed, the color is | black |
| When all the colors are being reflected into our eye, the color of the object is | white |
| A mirror that is curved IN is | concave |
| The back of the spoon curved outward is a _________ mirror | convex |
| A magnifying glass is like a | convex lens |
| The rearview mirror or dept. store mirrors are examples of | convex mirrors |
| Light travels in _____ lines. | straight lines |
| Light can travel through empty space. True or False? | true |
| Sound Can NOT travel through _______. | empty space. |
| Are light waves slower than sound waves? | NO |
| Sound needs a _________to travel through or we couldn't hear it! | medium |
| Does sound travel faster through air or metal? | metal |
| Amplitude is the | height of a sound wave, how loud the sound is. |
| Top part of a wavelength? | crest |
| Bottom part of a wave is the | trough |
| Crest to crest is a | wavelength |
| The ________is a receiver of light. | eye |
| Between air, brick, or glass, which material does sound travel fastest through? | Glass-it is more dense |
| The higher the pitch of a sound, the frequency increases or decreases?.... | increases |
| If the pitch lessens, then the frequency | also lessens |
| Light does not travel through _________objects: transparent, translucent, or opaque? | opaque |
| Light travels best through what type of objects? | transparent objects |
| Describe how a wave would look if the frequency was high and amplitude was very soft. | The wavelengths would be short (close together) and the height of the wave would be short. |
| Waves are a transfer of | energy |
| True or False. Ultraviolet, radio waves, microwaves and visible light are part of the electromagnetic spectrum. | True |
| If you are on team ozone, email mrs. young the correct answer for a treat to this question....I see a reflection of Tom Brady behind me in the mirror I'm holding up. Tell me the order the light would follow from source to receiver. | paulayoung@ga.ozark.k12.mo.us |
