wave characteristics
a rhythmic disturbance that carries energy through matter or space
what is a wave?
the complete spectrum of all forms of light
what is the electromagnetic spectrum?
when a wave hits an object and bounces off
what is reflection?
the speed of sound
what is 344 m/s
the lowest point of a wave
what is the trough?
a wave that needs a medium to transfer energy through
what is a mechanical wave?
an example of radio waves
what is radios/phones?
the bending of a wave when passing from one medium to another
what is refraction?
the highness or lowness of the sound that depends on frequency
what is pitch?
the highest point of a wave
what is a crest?
a wave that doesn't need a medium
what is an electromagnetic wave?
radio waves, micro waves, infrared waves, visible light waves, ultraviolet rays, x-rays, gamma rays
what is the electromagnetic spectrum?
the bending of a wave as it moves AROUND obstacles or through an opening
what is diffraction?
the volume of sound that depends on amplitude or energy
what is intensity?
consist of electric and magnetic fields which vibrate
what is electromagnetic waves?
the number of waves passing a point in 1 second
what is frequency?
the wave with the highest energy level in the electromagnetic spectrum
what are gamma rays?
the interaction of 2 or more waves that combine in a region
what is interference?
absorbs or reflects all light
what is opaque?
when two waves collide and cancel each other out
what is deconstruction interference
the distance between two crests or two troughs
what is a wavelength?
the color spectrum we can see with the naked eye
what is ROY G BIV?
the change in frequency caused by the movement of the source or listener
what is the doppler effect?
allows only some light through and absorbs the rest
what is translucent?
s=f•λ
what is the equation for wavelength?
