(34 cards)
Basilar Membrane
a membrane in the cochlea that is in the organ of Corti.
Sonar
a system for the detection of objects under water and for measuring the water’s depth by emitting sound pulses and detecting or measuring their return after being reflected.
Photon
a tiny particle of light or electromagnetic radiation
Intensity
intensity is the power transferred per unit area, where the area is an imagined surface that is perpendicular to the direction of the energy.
Radar
an electronic system used to detect,range and velocity
Light Ray
An imaginary line that follows behind in the direction that light travels.
Virtual image
Not the real image you see. It is an apparent path of light rays.
Real image
Opposite of virtual image rays are gathered into a single point or small area.
Diffuse reflection
Where random light is reflected off into many random directions, such as a disco ball.
Geometrical optics
Where light starts to perform like a ray.
Angle of reflection
The way the ought reflects off a smooth surface
Angle of incidence
The way a light Ray strikes a surface
Law of reflection
That the laws of reflection and incidence are the same angles
Normal
Where light hits an object
Convex mirror
Mirrors that cave outwards
Concave mirrors
Mirrors that cave in
Total internal reflection
complete reflection of a ray of light within a medium such as water surrounding the back into the medium.
Lens
Focuses all light into one hole.
Magnification
Duplicating wavelengths to make objects appear larger.
Prism
Used to disperse light
Dispersion
Where light is not appeared the way it really is
What is a sound wave
Sound waves are when an object is vibrating free air around it making noise
What is pitch
The pitch is affected by what the size of a vibrating object is the larger it is the lower the pitch the smaller it is the higher the pitch
What is infrasound
You can hear all infrasound
