a disturbance involving transfer of energy from one place to another
What is a wave?
the section which lies below the equilibrium position
What is a trough?
This type of electromagnetic wave has a shorter wavelength than visible light, but longer than X-Rays. Examples of this type of electromagnetic wave are tanning beds, black lights and lighting used to disinfect medical tools and equipment.
What is ultraviolet rays/waves?
This type of wave interaction is normally used everyday, if you like personal hygiene such as brushing your teeth, fixing your hair, flossing, or just looking at yourself as it involves the bouncing of a wave after it hits a medium.
What is reflection?
The order of speed for a sound wave through different mediums from slowest to fastest.
What is gas, liquid, solid?
a wave that requires a medium. A sound wave can be an example of this.
What is a Mechanical Wave?
The measurement that can be done 3 ways: crest to crest, trough to trough or from start to beginning
What is wavelength?
This type of electromagnetic wave has the longest wavelength and the lowest frequency. It can be observed with cell phones, televisions and wifi internet.
What is radio waves?
This wave interaction is the reason why you can hear students in the hallway when you are in the classroom.
What is diffraction?
The order of speed for a light wave through different mediums from slowest to fastest.
What is solid, liquid, gas, vacuum?
this type of wave has its energy travel perpendicular (at right angles) to it
Name and draw the greek symbol for wavelength
What is (λ) and a lambda?
This part of the electromagnetic spectrum has the shortest wavelengths and the highest frequency. Examples of this can be observed in stars, lightning as well as in the medical field to kill cancerous cells.
What is gamma rays?
This wave involves ultraviolet rays passing through a liquid medium allowing the light wave to change its speed, while creating a spectrum of color in different angles
What is refraction?
Radio wave that stands for Frequency Modulation because it travels in a straight line passing the ionosphere causing it to not have a wide-range.
What is an FM wave?
this type of wave has its energy travel parallel to it. A sound wave can also be an example of this!
What is a longitudinal wave?
the number of complete waves that pass a point in a given time
What is frequency?
This part of the electromagnetic spectrum is the part humans are able to see. It ranges in wavelength to display the colors red, orange, yellow, green, blue, indigo and violet (ROY - G - BIV).
What is visible light?
What is scattering?
A radio wave that bounces off the ionosphere therefore it has a wider range allowing them to reach hundreds of miles from the station. Although that is so, these radio waves have a poorer sound quality.
What is an AM radio wave?
a wave that emits radiation therefore they are light waves which allow them to travel through a vacuum
Hertz units measure the number of vibrations per second. If 624 vibrations pass by in one second, how many Hertz is this?
What is 624 Hz?
This part of the electromagnetic spectrum is used by the military as well as public officials. It has a longer wavelength than visible light but shorter than microwaves. These waves can be observed in heat sensing cameras, rifle scopes and cameras on aircraft to see moving targets at night. Mechanics also use them on engines to see if there are problems with one cylinder in an engine.
What is infrared waves?
This wave interaction occurs as the energy from a sound wave travels in curtains and the carpeted floor at a movie theater in order to result in vibrations being felt for your favorite movie.
What is absorption?
An increase or decrease in frequency due to motion. The observer or the source producing the wave is in motion. An ambulance driving closer to you is an example of this concept.
What is the doppler effect?
