Which types of light caused damage to plants?
Violet
Ultraviolet
Indigo
X-ray

If a plant (a) energy from ultraviolet light then it will become damaged.
If a plant (a) energy from a green light then the plant will not change.
Definition: Emit
To send out or give off something, such as light, heat, or sound.
A type of eradiation that travels as a wave through space and carries energy
The distance from one lightwave to the next
The height of a lightwave
Definition: LIGHTWAVE
To send out or give off something, such as light, heat, or sound.
A type of radiation that travels as a wave through space and carries energy
The distance from one lightwave to the next
The height of a lightwave
Definition: WAVELENGTH
To send out or give off something, such as light, heat, or sound.
A type of eradiation that travels as a wave through space and carries energy
The distance from one lightwave to the next
The height of a lightwave
Definition: AMPLITUDE
To send out or give off something, such as light, heat, or sound.
A type of eradiation that travels as a wave through space and carries energy
The distance from one lightwave to the next
The height of a lightwave
The shorter the WAVELENGTH the (a) the energy.
The longer the WAVELENGTH the (a) the energy.
Changing the WAVELENGTH changes the (a)
Match the WAVELENGTH with the amount of energy:
High Energy
Medium Energy
Low Energy
What LIGHTWAVES damaged plants?
Ultraviolet
Violet
Gamma
X-Ray
What do all the LIGHTWAVES that damaged plants have in common?
If Gamma Rays, X-Rays and Ultraviolet Lightwaves have enough energy to damage a plant, what else do you think they can cause damage to? (Think back to the unit question.)
What is the only type of light you can see with the naked eye?
Gamma Ray
X-Ray
Ultraviolet
Visible Lightwaves
Infrared
Match the interactions
Absorb
Reflect
Transmit
An object can only change if it (a) the energy from a lightwave.
An object will not go through a change if it:
reflects
absorbs
transmits
