If a toy sits out in the sun every day for a long time, can light from the sun damage the toy's paint?
Yes. The paint can take in energy from the light, causing it to be damaged.
No. Light can only change things by warming them up, so it cannot damage the toy's paint.
No. Light is not a physical thing, so it cannot change physical things like paint.
Yes. Light from the sun can pull energy out of the paint, causing it to be damaged.
How do we know that light carries energy?
We saw light cause matter to move or change, which is evidence that light carries energy.
We do not know that light carries energy.
Because light is bright so there must be energy present.
We saw light make objects glow in the sim, which is evidence that light carries energy.
Energy is...
the ability to have power.
the ability to make something move or change.
power.
electricity.
The movement of energy can be tracked by observing the (a) the energy causes to matter.
A light source can emit more than one type of
(a)
In our lab, the regular flashlight left the beads white or clear, but the UV flashlight made them change colors. Which claim does this evidence support?
There is only one type of light that changes material in the same ways.
There are different types of light that change material in the same ways.
There are different types of light that can change a material in different ways.
There is only one type of light.
A scientist measures the amplitude and wavelength of waves in the ocean. The scientist also calculates the amount of energy contained in one square meter of water for each wave. The data and calculations for four different waves are shown in the table.
Which wave characteristics, if any, does the energy in the wave depend on?
neither amplitude or wavelength
both amplitude and wavelength
wavelength only
amplitude only
Different types of light have different (a) .
How does increasing the amplitude of a wave affect the sound or light it produces?
Increasing the amplitude affects the intensity of the wave. Sound waves will be louder, and light waves will be brighter.
Increasing the amplitude affects the type of wave. Sound waves have a higher amplitude, light waves have a lower ampltiude.
Increasing the amplitude affects the intensity of the wave. Sound waves will be less loud, and light waves will be less bright.
What happens when the wavelength of a light wave is changed?
If the wavelength is changed, no characteristics of the wave change.
If the wavelength is changed, it becomes a sound wave.
If the wavelength is changed, the brightness of the light being emitted changes.
If the wavelength is changed, the type of light being emitted changes.
Here are two different waves:
What conclusion can you make about these two waves?
Only A has a wavelength.
Only B has a wavelength.
Both of them carry energy from one place to another.
Both of them represent light waves, but not sound waves.
What is the relationship between wavelength and frequency?
Wavelength is more related to sound and frequency is more related to light.
The shorter the wavelength the lower the frequency.
The shorter the wavelength the higher the frequency.
Scientists study frequency, they don't care about wavelength.
Examine the diagram. Waveform A caused damage to the material that absorbed it. Based on this observation, which waveform would be least likely to cause damage if absorbed by that same material?
Waveform B
Waveform C
Waveform D
None of the waveforms would cause damage.
The matter glowing when placed on the testing platform in the sim demonstrates...
The matter is not absorbing the light or the energy carried by the light.
The matter is absorbing the light but not the energy carried by the light.
The matter is absorbing the light and therefore the energy carried by the light.
The matter is not being affected by the light beam.
What is being modeled in the circle on the diagram?
The light is absorbing the energy from the genetic material.
The genetic material is damaging the sunlight.
Energy is being reflected off the genetic material.
Energy from the light is absorbed by the genetic material.
