sound and light Flashcards
What is a pitch?
A pitch is a high sound and a low sound that is perceived that is also depending on the frequency of all the sound waves
What is a sound wave?
A sound wave is a longitudinal waves that is caused by a vibration under the water and a sound wave travels through a material
What is a Infrasound
frequencies below the lower limit of human audibility.
What is a Ultrasound?
A ultrasound is any sound wave with frequencies
What is a Resonance?
A resonance is when you have to object that naturally come together vibrating with the same frequency
What is a Intensity?
the measurable amount of a property, such as force, brightness, or a magnetic field.
What is a Decibel?
a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
What is a Fundamental Frequency?
the lowest frequency produced by the oscillation of the whole of an object, as distinct from the harmonics of higher frequency.
What is a harmonic?
a component frequency of an oscillation or wave.
Sonar
A sonar is a sounds agitation and ranging that is also determine that location of an object
Basilar membrane
A
Photon
A unit of lights and some particles of electromagnetic radiation that has no rest massaged will also carry out a quantum of energy
Intensity
The rate at which energy flows through a given space of area
Radar
A radio that reflects a radio wave to determine velocity and locate objects.
Electromagnetic spectrum
All of the frequencies or wave lengths of electromagnetic radiation.
Light Ray
A space that is matching a flow of the radiant energy
Virtual image
A light Ray that can appear from the location
Real image
The image that is a object that can be formed by a light Ray and come together
Diffuse reflection
A movement of particles that can form a high density
Geometrical optics
A satellite that moves in earth and the satellite remains a altitude
Angle of reflection
A Angle that is formed by a line and can reflect when a ray moves.
Angle of incidence
An angle that is that a ray can strike back at a surface and the surface can be perpendicular to the point of contact.
Law of reflection
A law that is stating to the angle of incidence that is equal too.
Normal
A
Convex mirror
A
Concave mirror
A mirror curved inward.
Total internal
Takes place within a substance that is a surface boundary is less critical.
Reflection
A
Lens
A transparent object that the sun or something is shining on the lens can reflect
Magnification
A size in a image that is comparing to the side of the object
Prism
Two or more planes surfaces that has a solid going at a different angle
Dispersion
Separates the lights like if you had a whit light then different frequencies will divide into different waves
Mirage
A
Converging lens
A
Focal point
A
