What is one difference between white light and UV light?
UV light caused the glow in the dark star to glow brighter and for a longer amount of time. UV light caused the beads to change color.
White light caused the crytal paper to change color
What is the name of the type of light that has the largest wavelength?
Radiowave
Light that is absorbed and then re-radiated off in a new direction
Reflect
What is the definition of light?
Something that carries energy from one place to another
What do we use light for?
any reasonable answer ex: seeing in the dark, plants use it for photosynthesis
What happened to the solar powered toy when we shined the flashlight on it?
It started moving/dancing
What happens in a plant when it absorbs sunlight?
It gets warmer, ges damaged, and goes through photosynthesis
When light passes through an object
Transmit
Define emit
to give off
What is a light source and what is an example?
An object that emits light. Sun, light bulb, laser
What does the World Sunlight Map tell you about how much sunlight Australia gets compared to Brazil? Egypt? Japan?
Same amount of light as Brazil
Less light than Egypt
More light than Japan
It glows, it changes
When light is bent when it passes from one material of one density into a material of another density.
Refracted
Define visualize
to form a mental picture of something that cannot be seen
Is all light the same?
No, light is not the same. Different types of light have different effects on materials.
Why does light have an effect on materials?
Light has an effect on thungs because it has energy and that energy has the ability to make things move or change.
How does light cause skin cancer?
Some types of light can cause skin cancer by tranferring energy to a skin cell. The genetic material in the cell aborbs the energy and becomes damaged.
Light waves can have different wavelengths. What is a wavelength?
The distance between 2 points on a wave
An object that emits light
Light source
What must happen for light to change a material?
The material must absorb the energy from the light
What does the World Skin Cancer Map tell you about how the skin cancer rates of Australia and Brazil differ?
Australia has higher rates of skin cancer
In what ways can light change genetic material?
Increase kinetic energy
Damage
How do lightning and thunder illustrate the relationship between light and sound waves?
Light moves faster than sound, so you hear thunder after you see lightning.
Ultraviolet (UV)
A type of light with a short wavelength and high intensity
In our simulation, what is the one obect that did not change from light from the sun?
Aluminium
