Mechanical & Electromagnetic Waves
This is how a wave is created.
What is a disturbance causing vibrations in a medium?
This is the term for the maximum displacement of the wave from its midpoint to its crest
What is Amplitude?
FILL IN THE BLANK: ___________ waves travel fastest in more dense media, while ____________ waves travel fastest in a vacuum (less dense).
SOUND, LIGHT
**ALSO: Mechanical, Electromagnetic
When waves bounce off of a surface, this is called...
What is Reflection?
Lenses operate on the light wave property of...
What is Refraction?
This the material through which a wave travels.
What is a medium?
When waves bend as they travel THROUGH a material, this is called...
This type of lens is thicker in the center and causes light to converge, or meet in the middle.
What is a convex lens?
These are the names for the two main types of mechanical waves.
What are Transverse Waves and Longitudinal Waves
This property of a wave affects a sound's pitch, or a light wave's color.
What is the **frequency**?
Will also accept **wavelength**
When waves travel and bend AROUND an object, this is called...
What is Diffraction?
This type of lens is thinner in the middle, and it causes light to diverge, or split apart.
What is a concave lens?
This type of wave is formed by an electric field and a magnetic field continuously regenerating each other.
These are the three factors that affect the energy of a wave.
What are frequency, wavelength and amplitude?
This property of a wave affect's a sound wave's volume, or the brightness of color.
What is the **amplitude**?
We observe that a person is wearing an orange shirt. The reason it appears orange to us is due to the property of...
What is Reflection?
What type of lens is used for people who don't see well far away?
What is a concave lens?
This is the only portion of the electromagnetic spectrum that humans can see with the naked eye.
What is the visible light spectrum?
These two parts of a wave are needed to complete an entire wave cycle (equal to 1 Hz).
What is a crest + a trough?
This phenomenon changes our perception of color or sound (think of a passing ambulance) due to a change in wavelength and frequency as an object passes us by.
What is the Doppler Effect?
If an orange shirt reflects orange, all of the other colors of light undergo the process of...
What is Absorption?
This type of image results in a convex lens only, and we see it on the opposite side of the lens from the object, and upside-down.
What is a REAL image?
