Light
Light waves are considered what type of wave
Transverse
Sound waves are considered what type of wave?
Mechanical
The shorter the wavelength the _____ the frequency
higher
What is the top and bottom of a wave called?
Crest and Trough
What is the height of the wave from its resting point called?
Amplitude
Light travels the fastest in which medium? Why?
Space (Vaccum) because it is the least dense
Sound travels the slowest in which medium? Why?
Space, Because it needs a medium

The distance between corresponding or consecutive crests or troughs on a wave is called?
Wavelength
Name 2 EMS waves with a shorter wavelength than visible light?
gamma, xray, uv rays

There are many types of waves that require mediums. What is the name of a wave that does not require a medium
transverse or elctromagnetic
Many types of waves require a medium. What is the definition of a medium
A material or substance that a wave travels through
Sally puts a straw into a glass of water. She notices that when she looks through the glass and the water from the side, the straw appears to be broken. Which term BEST explains why the straw looks like it is broken and why?
refraction, light slows down when going into a denser medium
Compression or sound waves behave a lot like transverse or electromagnetic waves. Compression waves exhibit ALL BUT one of the following behaviors
a) Can travel through a vacuum (empty space)
b)Transfer Energy
c) Refraction
d) reflection
a
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and amount of energies. Which of the following has the highest frequency and therefore carries the largest amount of energy
gamma
Which type of waves carry energy at a right angle or perpendicular to the direction of the energy flow?
transverse
The visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow. Each color we see corresponds to a different wavelength of light. Which color of visible light has the shortest wavelength
violet
What are three different interactions that light can have when encountering matter? What are they and define each in a very short sentence
refract = light bends, reflect = light bounces, absorb = light goes into the matter
A Student tapped one end of a long wooden table. Sanjay and Marc listened for the sounds. Sanjay pressed his ear to the table and heard the tapes before Marc did. Why
sound travels faster through denser mediums
What is the relationship of wavelengths to frequency of ems waves
shorter wavelengths = higher frequency and vice versa
Caleb counts the number of ocean waves that pass the end of a pier in one minute. What property of waves does Caleb measure
frequency
Kana shines a light onto paper. The light contains both all wavelengths of visible light. If the paper is green why is the paper green?
because all colors except green are absorbed and the green is reflected
