Light
Electromagnetic Waves.
or EM Waves
What is the fastest type of wave?
Light wave
Name for the apparent change in frequency of the light observed due to motion of the source of light.
Doppler Effect of Light
What makes some EM waves safe and some dangerous?
They have different frequencies that carry different amounts of energy.
Name for when light bounces off of something, changing the direction of its path...
Reflection
The longest wavelengths are seen as which color on the visible light spectrum?
Red
All electromagnetic waves are ________ in that the direction of their disturbances are perpendicular to each other.
transverse
What color is observed the closer a light wave moves towards you?
Blue (Blue Shift)
Which wave on the EM Spectrum caused Bruce Banner to become the Incredible Hulk?
Gamma Rays (Long Live the Incredible Hulkamaniacs!)
Name one difference between EM Waves and Mechanical Waves.
EM doesn't need a medium, Mechanical does...Mechanical can be transverse and longitudinal, EM is only transverse.
The shortest wavelengths are seen as which color on the visible spectrum?
Violet
Which EM waves has the highest frequency and energy?
Gamma Rays
What color is observed the further a light wave moves away from you?
Red (Red Shift)
True or False: Radio and Microwaves have the LONGEST wavelength of the entire EM Spectrum.
True
What kind of waves are sound waves?
Longitudinal
What is the order of the visible light spectrum?
ROY G BIV
Red, orange, yellow, green, blue, indigo, violet.
What material does microwaves reflect off of?
Metals
Which light effect has more energy, blue shift or red shift?
Blue shift
Which two parts of the electromagnetic spectrum are close to visible light?
Infrared Light and Ultraviolet Light
True or False: Because X-rays have a shorter wavelength than UV waves, they have a higher energy level.
True
True or False: When light waves intersect each other, their waves pass through each other without any changes.
False
Someone from your team must recite the waves on the EM Spectrum (left to right) in order on the mic...you have one minute in chat as a group to think it through...
Radio, Microwaves, Infrared, Visible Light, Ultraviolet, X-Rays, Gamma Rays
If the universe is expanding, what color will stars eventually be from the perspective of earthlings?
Red (because of Red Shift)
Recite the colors of the visible light spectrum in order of increasing wavelength.
Violet, Indigo, Blue, Green, Yellow, Orange, Red
Why do we see a red apple as red?
Red is not in the apple. The apple reflects the red wavelength and absorbs all other wavelengths.
