Waves
What is a wave
Waves are repeating disturbances that carry energy from one place to another.
Definishion of a physical property.
Can be observed without changing the identity of the substance. Have you 5 senses to observe.
What is the lowest poinT on a transverse wave called?
The Trough
Whats the definition of X rays?
A tool used to view inside our body.
What kind of wave has a crest and a trough?
What is a mechanical wave?
Mechanical waves are waves that must have a matter medium in order to transfer energy.
What are some examples of Chemical Properties?
Flammability, , pH value, ability to rust, and ability to react to water.
What is the distance between adjacent wave compressions?
The wavelength
What are some examples of Ultraviolet?
Pens, passports, security, and money.
What kind of wave has rarefaction?
What is an electromagnetic wave?
An electromagnetic wave is made up of alternatlins electrical and do not require molecules to work.
What are all common clues that a Chemical change has occurred?
Gas is produced, color or oder change, solid precipitate formed, heat released or absorbed, light produced, bubbles or fizzing, sound given off.
what is the definition of a wavelength?
The distance from crest to crest or trough to trough. The shorter the wavelength the faster the energy is carried.
Definition of Visible light and shortest and longest wavelength.
Light used to see. Red is the longest wavelength, while violet is the shortest wavelength. They use light fibers to transfer energy.
A wave that can travel through matter or through the empty vacuum space.
Electromagnetic wave
What are good examples of a Longitude and Transverse wave?
A Transverse wave is a water wave and a Longitude wave is a sound wave.
How does frequency affect pitch in music?
In sound waves, the pitch relates to the frequency. The higher the pitch on a sound wave equals a higher frequency and a shorter wave length.
The speed of a wave in 65 m/sec. If the wavelength of the wave is 0.8 meters, what is the frequency of the wave?
Answer f=81.25Hz
What is the Infrared definition?
The Hotter the object the more it is Infared.
What’s something all waves have?
Energy
What is meant by a amplitude of a wave? What transfers more energy a wave with high or low amplitude?
The amplitude of a wave is related to how much a wave is moving. A wave with high amplitude transfers more energy then a wave with a low amphlitude.
What’s the definishion of frequency?
A wave with a frequency of 500 Hz is traveling at a speed of 200m/s. What is the wavelength?
Answer W=0.4m
What is the electromagnetic spectrum from the most energy to the least?
Gamma rays, X rays, Ultraviolet, Bisible light, Infrared, Microwaves, Radiowaves.
What’s an example of a Mechanical wave?
A seismic or earthquake wave.
