Mechanical Waves
What are the two types of mechanical waves AND their 4 parts?
Transverse = Crest & trough
Longitudinal = compression & rarefaction
What is the name of the wave with the highest frequency?
The distance from crest to crest or trough to trough is called ____ and the unit for this is ______.
Wavelength & Meters (m)
_____ is what determines the color we see objects
Absorption
Sound travels fastest through _____ because _____.
Solids because their particles are closer together.
The crest is the _____ point of the wave
Highest
Electromagnetic waves can travel through _____ and ________.
any medium and empty space
The distance from the origin to the crest or the origin to the trough is called
Amplitude
When light bounces off a surface it is called _
Reflection
Light travels slowest through ____
solids
The trough is the _____ point of the wave
Lowest
Which part of the EM spectrum is responsible for making you warm on a sunny day?
Infrared Waves
How many waves pass by a point in 1 second is called ____ and the unit for this is _____
Frequency & Hertz (Hz)
What happens to light when it interacts with matter?
Refraction
Sound travels in what speed for:
Solids = _______
Liquids = ______
Gases = _______
Solids = Fastest Speed
Liquids = Medium Speed
Gases = Slowest Speed
Which wave would require a medium?
A- EM Waves
B- Radio Waves
C- Sound Waves
D- Light Waves
C
Which one of these would be a radio wave?
(Ms. Puello will pull up the picture of the question)
A
Why do some electromagnetic waves have more energy than others?
Because they have different frequencies
Why would an apple look red?
Apples reflect red light and absorb all the other colors of ROY G BIV
If a fish and a cow both produce a sound when they are 16 meters from an object, which animal would hear its echo first?
The fish because sound travels faster through water than through air.
An EM wave is technically considered to be a _______ wave because they have similar properties.
transverse
Which two waves have the same wavelength?
(Ms. Puello will pull up the picture of the question)
A and C
What is the relationship between the energy, wavelength and frequency of a wave?
What happens when light passes from air to water?
REFRACTION
It bends- there for it slows down
Here is the question rephrased:
12. Sound moves more quickly through solids compared to liquids or gases. What measurements would a student need to take to confirm this observation?
A. The length that sound travels in a solid, a liquid, and a gas.
B. The frequency of sound as it moves through a solid, a liquid, and a gas.
C. The length sound travels in a solid, a liquid, and a gas at different temperatures.
D. The time it takes for sound to cover a specific distance in a solid, a liquid, and a gas.
D
