Waves test review Flashcards
The waves that carry the most amount of energy are the waves that have the greatest.
Amplitude
What is the main difference between a transverse and a longitudinal wave?
Transverse waves move up and down while longitudinal waves move left and right.
What is the main difference between a mechanical and electromagnetic wave?
Mechanical waves need a medium and electromagnetic waves don’t need a medium.
What are the different parts of a transverse wave?
Crest , and Trough
What are the different parts of a longitudinal wave?
Compression, and Refraction.
Name 3 different applications of the reflection of waves (light, sound, heat).
Type of Wave Application of reflection of the type of wave
Light wave:
Sound wave:
Heat wave:
Mirror
Hard Surfaces
Tin foil
What is a medium?
Any material substance a wave can travel through.
Name the mediums for a sound wave, arm wave, and an oceanic wave.
Type of Wave Medium for the wave
Sound wave:
Arm wave:
Oceanic wave:
Air
Body
Water
What are the 7 different electromagnetic waves we discussed in class?
Radio, microwaves, infrared, visible light, Uv light, X-ray, and Gamma ray.
What color of the visible light spectrum has the longest wavelength and lowest frequency?
Red
What color of the visible light spectrum has the shortest wavelength and highest frequency?
Violet
Explain why it is important for someone who goes spear fishing to know what refraction is.
If they don’t know what refraction is they are not going to know how to re adjust and they won’t catch anything.
Name at least 2 applications of diffraction that we discussed in class.
When light goes into the room it spreads out, and when sound goes around an obstacle.
What is an application of constructive interference that we have discussed in class? Explain how it works.
Constructive interference is when two waves combine with each other and make a bigger an example of this is the viking clap.
Type of Wave: Mechanical, electromagnetic, transverse, longitudinal
(list all that apply for each)
Sound wave
Light wave
Oceanic wave
Mechanical, and longitudinal
Electromagnetic, and transverse
Mechanical, and transverse
Noise cancelling headphones emit a sound wave that disrupts or cancels an incoming sound wave. This utilizes a wave behavior called __________________.
Destructive interference
Name the 2 different parts of the coil for #17 when they are really close together they are and when they are far apart they are?
Compression, and refraction
The highest point of the wave?
Crest
The lowest part of the wave?
Trough
The middle points of the wave?
Wavelength
When the pencil is in a glass of water and it looks like it is cut in half this an example of?
Refraction.
Is radio, microwaves, and Infrared wavelength long or short and is its frequency high or low?
The wavelength is long and the frequency is low.
Is Ultraviolet, X-rays, and Gamma wavelength long or short and is the frequency high or low?
They have a short wavelength and a high frequency.
What is ROYGBIV
Red, Orange, Yellow, Green, Blue, Indigo, and violet these colors make up visible light.
