What are the two forms of energy that are transferred in an electromagnetic wave?
Electricity and Plasma
Electricity and Magnetism
Magnetism and Plasma
Electricity and Ectoplasm
Electromagnetic Waves are what type of waves?
Surface
Longitudinal
Transverse
Mechanical
Electromagnetic Waves are NOT considered Mechanical Waves because......
They can only penetrate certain kinds of matter
They can cause harm to living cells after prolonged exposure
They don't require a medium to travel through
Because you can't surf on them (Shut up Spicolli!)
The photoelectric effect demonstrates which model regarding wave behavior?
(a)
What is The Law Of Waves?
If you have waves....SURF! (SHUT UP SPICOLLI!)
As wavelength increases, frequency increases
As wavelength decreases, frequency decreases
As wavelength decreases, frequency increases
As wavelength increases, frequency decreases
What form of electromagnetic waves have the longest wavelengths and lowest frequencies
(a)
The form of electromagnetic waves are used to cook food, used in cellular / smart phones, they can also be manipulated to be used in RADAR or LIDAR
Radio waves
Microwaves
Infrared Waves
Visible Light
This type of electromagnetic wave is used to take pictures which show temperature. What are they? (Not the name of the picture, the name of the wave)
(a)
The smallest portion of the electromagnetic spectrum that we can actually see is called what?
(a)
These types of electromagnetic waves have lots of energy and can cause damage to human tissue over a prolonged time. Despite this, short exposure to them is not dangerous and they are often used to examine a human body's internal structure as they can penetrate all but the most dense of matter. What are they?
(a)
These waves have the shortest wavelength of all electromagnetic waves but the greatest frequency. They are used here on Earth to examine a body's internal structures but they can also be found in space, what type of wave are they?
(a)
The difference between electric radios and smart phones is what?
(a)
Which of the following is NOT an electromaGNETIC WAVE?
Visible Light
Sound
Gamma
X-Ray
True OR False....Electric and Magnetic fields produce each other repeatedly.
True
False
A polarizing filter does what?
It filters out all UV rays and only lets the good light through.
It creates a two-way filter that only lets waves that are vibrating go through in two directions.
It only lets waves through that are vibrating in a certain direction.
It lets NOTHING through and polarizes everything
What would you add to the picture below to ensure that light does NOT hit the final screen?
Another light bulb
Another filter, but one with vertical slits
Another filter, but one with horizontal slits
A heat source
Visible Light is a mixture of:
Reflection and Refraction
Atoms and molecules
Many colors (ooooh! Pretty colors!)
Ultraviolet and non-violet rays
The Sun emits Ultraviolet waves. We know that these can be harmful to living cells and after prolonged exposure, cause cancer. They are able to reach the Earth because:
Their wavelengths are short, which makes them have higher amounts of energy
They have more energy than infrared rays
They have a lower frequency than visible light
They do not require a medium to travel through
Gingies be crispy
When Hurricane Sandy came ashore in New Jersey in 2012. Many people (My father and sister included) lost power for an extended period of time. Which of the following technologies would be best to have to receive news updates in that area at that time?
A battery powered device that can receive AM / FM radio waves
A battery powered device that can receive ultraviolet rays
A battery powered GPS receiver
A battery powered X-Ray machine
A town crier or a newspaper
Radio waves carry information from what to what?
Antenna to antenna
Amplitude to frequency
AM to FM
Space to Earth
Your ear to your brain
True or False: AM radio waves have longer wavelengths than FM radio waves
True
False
True or False: AM radio waves travel a shorter distance than FM radio waves.
False
True
The government body that regulates broadcasting in the United States is called what?
(a)
Digital radios take radio waves and transfer them into what?
(a)
Using a satellite phone system you can call anywhere in the:
County
State
Country
Planet
Solar System
