Mechanical vs Electromagnetic Waves
What type of wave is sound?
A mechanical wave
What do we call light bending when it enters a new material?
Refraction
More amplitude means more what?
More energy
Shortening wavelength from violet in the Sim moves the wave toward which type of light?
Ultraviolet (UV)
n a wave diagram, what does the horizontal distance between crests represent? (Crest to Crest)
Wavelength
What type of wave is light?
An electromagnetic wave
What behavior of light does a mirror show?
Reflection
Why is the sound louder when a book is dropped from a higher height?
More energy transfers into sound.
Which types of light in the Sim caused no change to genetic material?
Radio, microwave, infrared, and visible light
In a wave diagram, what does the height from the midline to the crest represent?
Amplitude
What do mechanical waves need that electromagnetic waves do not?
A medium (matter)
Materials that let most light pass through them do what with light?
Transmit it
Which wave property determines the type of light?
Wavelength
Why does increasing wavelength from UV shift light toward infrared?
Longer wavelengths like IR carry less energy.
If a wave hits a boundary at an angle, what will the reflected wave do?
Reflect at the same angle
Why can sound travel through air but not through space?
Space has no molecules to transfer sound.
Which wave behavior occurs when a wave bounces off a boundary?
Reflection
How does sound energy travel from an object to your ear?
Vibrating molecules compress and expand, carrying energy.
How did the Sim show which types of light damage DNA?
UV light caused changes in the genetic material model; others did not.
If Light Source 2 causes damage but Light Source 1 only causes warmth, which waveform matches Light Source 2?
The one with the shortest wavelength and highest energy
Using wave models, explain why sound and light behave differently in space.
Sound requires vibrating particles; light travels without particles.
Why do some materials absorb certain wavelengths but allow others to pass?
Different wavelengths interact with different types of matter for many reasons.
Why can two waves with the same amplitude have different effects on materials?
Wavelength determines energy and type of interaction.
Gamma
Why does the sound wave diagram show particle movement but the light wave diagram does not?
Sound requires matter to travel; light does not.
