Sound And Light Flashcards
Refraction
The way that light bends when they slow down.
Plane mirror
It is the reflected surface
Cornea
It is the front part of the eye that is transparent
Oscillation
It is a repetitive variation in time.
Speed of sound
It is the distance
Diffuse scattering
When light is reflected off a surface in all directions.
Frequency
The number of waves produced each second. The unit of frequency is Hertz (Hz).
Incident ray
Light ray moving towards a surface or boundary.
Lens
A transparent tool that can change the direction of a ray of light.
Reflected ray
Light ray leaving a surface or boundary.
Retina
The light-sensitive area on the back of the eye. Light must be focused on the retina in order to see clearly.
Spectrum
A series of similar waves arranged in order of wavelength or frequency.
Vacuum
A volume that contains no matter.
