Waves
Cannot transmit energy in a vacuum
What are Mechanical Waves?
High points of Transverse Waves
What are Crests?
The highness or lowness of a sound
What is pitch?
The bending of Light
What is refraction?
Cooking food; transmitting sound via satellites to phones...
What are Microwaves?
An observed change in the frequency of a wave when the source or the observer is moving
What is the Doppler Effect?
Half the vertical distance from the trough to the crest of a wave
What is Amplitude?
A reflected sound wave
What is an echo?
When the crest of one wave overlaps with the trough of another, the resulting amplitude of the combined waves is less than the amplitude of either of the original waves.
What is Destructive Interference?
Particles
What are Photons?
Waves in which the motion of the particles is perpendicular to the motion of the waves
What are transverse waves?
The distance from a consecutive trough to trough or Compression to Compression
What is wavelength?
Sound that has a frequency greater than 20,000 Hz
What is ultrasound?
Mirrors that curve inward at the center.
What is a Concave Mirror?
Can be described in terms of energy, wavelength, or frequency
What is Electromagnetic Radiation?
Waves that vibrate parallel to the motion of the wave’s movement
What are Longitudinal Waves?
the number of waves that pass a specific point in a given time
What is Frequency?
the amount of energy that is transported per unit time past a given point of the medium through which the sound travels
What is Intensity?
Light waves that vibrate in one direction.
What is polarized light?
Energy transmitted by electromagnetic waves
What is Radiant Energy?
A group of transverse energy waves that can transmit energy in a vacuum
What are electromagnetic waves?
Calculated by multiplying wavelength and frequency
What is Wave Speed?
What is absorption?
Theory states that a beam of light will reflect off a surface at the same angle at which it struck the surface
What is the Law of Reflection?
Shortest wavelength, highest frequency on Electromagnetic Spectrum.
What are Gamma Rays?
