Visible Light
A light wave with a high amplitude will be...
Bright
Sound can travel through empty space.
True or False?
False
What type of wave is all light?
Transverse
The top peak of each wave is called a trough.
True or False?
False
Crest
Bees and other insects see using...
Ultra Violet rays
This is the coldest color, with the longest wavelength.
Red
How does sound travel?
Via longitudinal compression waves requiring matter/substance to move.
Shining light through one of these splits it into all seven colors.
Prism
What does frequency measure?
How many wave crests pass a given point per second.
Name two sources, besides the sun, of EM radiation.
Radios, cell phones, televisions, laptops...
This is the most energetic color in the rainbow with the greatest frequency.
Violet
A sound wave with a high amplitude will be...
Loud
Name all categories of radiation from least energetic to most.
Radio, Micro, Infrared, Visible Light, Ultra Violet, X-Ray, Gamma Rays
This property is a measure of how large the wave is/the magnitude.
Amplitude
Name three professions that utilize EM waves.
Radiologists, Astronomers, and Military Operatives
Define all of the following:
Absorption
Refraction
Transmission
Reflection
Light is absorbed and does not pass through.
Light is bent.
Light passes through.
Light bounces back.
Define "medium".
The type of matter through which a sound wave flows.
ex: earth, air, water, glass...
Describe the relationship between wavelength and frequency.
The shorter the wavelength, the higher the frequency. They have an inverse relationship, meaning that as one increases, the other decreases.
Frequency is measures in...
Hertz
Thermal imaging and night vision goggles both use...
Infrared Waves
Explain color and how it relates to the age of stars.
The older the star, the redder the color. The newer the star, the bluer the color because it burns hottest.
How many times does sound travel faster through metal than air?
18
Plants are green.
Why?
TD.
Wavelength is measured in...
Nanometers
Earthquakes are examples of all three types of waves.
How do you know?
TD.
