You wear a dark-colored shirt outside in the early spring to stay warm. This works because the shirt
reflects lots of sunlight
transmits lots of sunlight
refracts lots of sunlight
absorbs lots of sunlight
You wear a light-colored shirt outside in the mid-summer to stay cool. This works because the shirt
reflects lots of sunlight
transmits lots of sunlight
refracts lots of sunlight
absorbs lots of sunlight
Your pale-skinned friend notices her arm sunburns when the car window is down but not when the window is kept up. What can you infer?
The car's window glass transmits lots of ultraviolet.
The car's window glass reflects lots of ultraviolet.
The car's window glass transmits lots of infrared.
The car's window glass reflects lots of infrared.
You have some green cling film (plastic wrap). You hold some film up to the light and realize the film appears green because
the film reflects more green wavelengths.
the film transmits more green wavelengths.
the film absorbs more green wavelengths.
the film emits green wavelengths of light.
You continue pondering the green cling film. You realize it appears green because
the film reflects colors other than green
the film transmits colors other than green
the film absorbs colors other than green
the film emits colors other than green
This diagram of the electromagnetic spectrum reminds us that
all light waves have similar wavelengths.
gamma rays are relatively low-energy waves.
radio waves have very short wavelengths.
visible light is a very small part of the spectrum.
Which statements correctly describe how sound waves and light waves differ? Check all that apply.
Sound waves travel faster than light waves.
Sound waves are longitudinal waves.
Light waves are transverse waves.
Light waves can travel with or without a medium.
Sound waves can travel with or without a medium.
